I have been taking these same herbs for 6 months and I have lost over 30 lbs. I have researched each herb and have found that they all help in some way for weight loss, cleanser and many other things. I feel wonderful and have recommended these to many many people who are concerned about their health. I have a daughter who could use them, however, I have not allowed her to take them for fear that she may think it is ok to take any "diet" pill to lose weight. I really don't think there is anything in it that would hurt her, I just don't want her to feel like she is taking something to lose weight.

The herbs in this formula are fine, but these Pills have beed recalled by the FDA. They contain harmful pharmeceuticals. I was planning to order them wholesale and sell them, but I discovered the warning. you can go to FDA website for the list.

Do you think that the herbs in the 2 day diet japan lingzhi have any interactions with prescription medicine?

Lingzhi, Ebiny, Fox Nut, Tuckahoe, Seman Pruni, and Dioscoreae are some of the ingredients. I dont think they react with meds, but watch out for liver problems and thyroid problems after you stop taking them. While you may be having increased bowel movements with the pills, there is a chance that they wont be regular afterwards (constipation).

What are some examples of how fungi are important to humans?

Medicine:-Fungi of the genus Penicillium are how humans discovered antibiotics - first Penicillin, and following were many, many more.-Lovastatin is a cholesterol-lowering drug that is naturally produced in the Oyster Mushroom (Pleurotus ostreatus)-The Reishi, or Lingzhi, mushroom (Ganoderma lucidum) is highly prized and very well known in TCM (Traditional Chinese Medicine). It is an immune system stimulant, contains natural steroidal compounds, and has mild ACE (acetylcholine esterase) inhibiting properties that may be useful in conditions like Alzheimer's Disease.-The prized edible and well known Chanterelle has a very high level of vitamin D.-There are many more medicinal- and health-benefiting mushrooms and fungiIndustry:-The velvety surface of Birch Polypore (Piptoporous betulinus) after being cut has historically been used as a strop to finish the edges of the finest of razors. It has also been used as tinder, and was found being carried by a 5,000 year old mummy in Tyrol.-Dyer's mushrooms are various fruiting bodies of fungi whose pigments are strong enough and of such chemical makeup that they are known to be effective fabric and yarn dyes.-Some fungi are capable of absorbing toxins like crude oil and heavy metals, and store these in non-dangerous ways or expel them in safe forms.Similar to medicine, I insist upon including psychoactive mushrooms as a tool to assist psychotherapy, personal growth, and introspect. They are possibly the oldest known 'intoxicant' used by man, and are referenced as 'Soma' in the oldest of texts, including the Rg Veda. The Aztecs refer to psilocybin-containing mushrooms as 'Teonanacatl' which literally translates to 'divine flesh' or 'God's flesh.'Food:Many fungi produce fruiting bodies known as mushrooms which are both delicious and health-promoting. Some of my favorites include:-Chanterelle complex - genus Cantharellus-Porcini - Boletus edulis-Candy Cap (Curry Milkcap) - Lactarius fragilis, Lactarius rubidus-Oyster Mushroom - Pleurotus ostreatus-Shiitake mushroom - Lentinula edodes-Reishi mushroom - Ganoderma lucidum-Noble Rot - Botrytus cinerea is a fungus that grows on grapes, stealing moisture from them, and eventually destroying a crop. However, if conditions are right, and infected grapes are picked at a specific point (being mostly raisinated by then) they can be used to create certain varieties of very fine dessert wines, like the French - Sauternes, and the Hungarian - Tokaji.There are many, many more important uses for fungi, but these are just the first few which came to my mind.

What in the world is a turtle?

Turtle From Wikipedia, the free encyclopediaJump to: navigation, searchFor other uses, see Turtle (disambiguation). Turtles are reptiles of the order Testudines (the crown group of the superorder Chelonia), characterised by a special bony or cartilaginous shell developed from their ribs that acts as a shield. "Turtle" may either refer to the Testudines as a whole, or to particular Testudines which make up a form taxon that is not monophyletic.The order Testudines includes both extant (living) and extinct species. The earliest known turtles date from 215 million years ago,[2] making turtles one of the oldest reptile groups and a more ancient group than lizards, snakes and crocodiles. Of the many species alive today, some are highly endangered.[3]Like other reptiles, turtles are ectotherms-their internal temperature varies according to the ambient environment, commonly called cold-blooded. However, leatherback sea turtles have noticeably higher body temperature than surrounding water because of their high metabolic rate.Like other amniotes (reptiles, dinosaurs, birds, and mammals), they breathe air and do not lay eggs underwater, although many species live in or around water. The largest turtles are aquatic.Contents[hide] 1 Anatomy and morphology 1.1 Neck folding1.2 Head1.3 Shell1.4 Skin and molting1.5 Limbs2 Ecology and life history3 Systematics and evolution 3.1 Turtle genera with basal or uncertain phylogenetic position3.2 Suborder †Proganochelydia3.3 Suborder Cryptodira3.4 Suborder Pleurodira4 Turtle, tortoise, or terrapin5 Distribution6 Fossil record7 Genomics8 As pets9 As food, traditional medicine, and cosmetics10 Conservation status11 In culture 11.1 On coins11.2 In heraldry12 See also13 References14 Further reading15 External linksAnatomy and morphologyChelonia mydas in Kona, Hawaii The largest living chelonian is the leatherback sea turtle (Dermochelys coriacea), which reaches a shell length of 200 centimetres (6.6 ft) and can reach a weight of over 900 kilograms (2,000 lb). Freshwater turtles are generally smaller, but with the largest species, the Asian softshell turtle Pelochelys cantorii, a few individuals have been reported up to 200 centimetres (6.6 ft). This dwarfs even the better-known alligator snapping turtle, the largest chelonian in North America, which attains a shell length of up to 80 centimetres (2.6 ft) and weighs as much as 113.4 kilograms (250 lb).[4] Giant tortoises of the genera Geochelone, Meiolania, and others were relatively widely distributed around the world into prehistoric times, and are known to have existed in North and South America, Australia, and Africa. They became extinct at the same time as the appearance of man, and it is assumed humans hunted them for food. The only surviving giant tortoises are on the Seychelles and Galápagos Islands, and can grow to over 130 centimetres (51 in) in length, and weigh about 300 kilograms (660 lb).[5]The largest ever chelonian was Archelon ischyros, a Late Cretaceous sea turtle known to have been up to 4.6 metres (15 ft) long.[6]The smallest turtle is the speckled padloper tortoise of South Africa. It measures no more than 8 centimetres (3.1 in) in length and weighs about 140 grams (4.9 oz). Two other species of small turtles are the American mud turtles and musk turtles that live in an area that ranges from Canada to South America. The shell length of many species in this group is less than 13 centimetres (5.1 in) in length. A red-eared slider turtle with eyes closer to the end of the head, keeping only the nostrils and the eyes above the water surfaceAfrican spurred tortoise at a zoo in the Czech RepublicNeck foldingTurtles are divided into two groups, according to how they evolved a solution to the problem of withdrawing their necks into their shells (something the ancestral Proganochelys could not do): the Cryptodira, which can draw their necks in while contracting it under their spine; and the Pleurodira, which contract their necks to the side. HeadMost turtles that spend most of their lives on land have their eyes looking down at objects in front of them. Some aquatic turtles, such as snapping turtles and soft-shelled turtles, have eyes closer to the top of the head. These species of turtles can hide from predators in shallow water, where they lie entirely submerged except for their eyes and nostrils. Sea turtles possess glands near their eyes that produce salty tears that rid their body of excess salt taken in from the water they drink. Turtles are thought to have exceptional night vision due to the unusually large number of rod cells in their retinas. Turtles have color vision with a wealth of cone subtypes with sensitivities ranging from the near ultraviolet (UV A) to red. Some land turtles have very poor pursuit movement abilities, which are normally reserved for predators that hunt quick moving prey, but carnivorous turtles are able to move their heads quickly to snap.Turtles have a rigid beak. Turtles use their jaws to cut and chew food. Instead of teeth, the upper and lower jaws of the turtle are covered by horny ridges. Carnivorous turtles usually have knife-sharp ridges for slicing through their prey. Herbivorous turtles have serrated-edged ridges that help them cut through tough plants. Turtles use their tongues to swallow food, but they cannot, unlike most reptiles, stick out their tongues to catch food.ShellMain article: Turtle shell The upper shell of the turtle is called the carapace. The lower shell that encases the belly is called the plastron. The carapace and plastron are joined together on the turtle's sides by bony structures called bridges. The inner layer of a turtle's shell is made up of about 60 bones that include portions of the backbone and the ribs, meaning the turtle cannot crawl out of its shell. In most turtles, the outer layer of the shell is covered by horny scales called scutes that are part of its outer skin, or epidermis. Scutes are made up of a fibrous protein called keratin that also makes up the scales of other reptiles. These scutes overlap the seams between the shell bones and add strength to the shell. Some turtles do not have horny scutes. For example, the leatherback sea turtle and the soft-shelled turtles have shells covered with leathery skin instead.The rigid shell means turtles cannot breathe as other reptiles do, by changing the volume of their chest cavity via expansion and contraction of the ribs. Instead, turtles breathe in two ways. First, they employ buccal pumping, pulling air into their mouth, then pushing it into the lungs via oscillations of the floor of the throat. Secondly, by contracting the abdominal muscles that cover the posterior opening of the shell, the internal volume of the shell increases, drawing air into the lungs, allowing these muscles to function in much the same way as the mammalian diaphragm.The shape of the shell gives helpful clues to how a turtle lives. Most tortoises have a large, dome-shaped shell that makes it difficult for predators to crush the shell between their jaws. One of the few exceptions is the African pancake tortoise, which has a flat, flexible shell that allows it to hide in rock crevices. Most aquatic turtles have flat, streamlined shells which aid in swimming and diving. American snapping turtles and musk turtles have small, cross-shaped plastrons that give them more efficient leg movement for walking along the bottom of ponds and streams.The color of a turtle's shell may vary. Shells are commonly colored brown, black, or olive green. In some species, shells may have red, orange, yellow, or grey markings and these markings are often spots, lines, or irregular blotches. One of the most colorful turtles is the eastern painted turtle which includes a yellow plastron and a black or olive shell with red markings around the rim.Tortoises, being land-based, have rather heavy shells. In contrast, aquatic and soft-shelled turtles have lighter shells that help them avoid sinking in water and swim faster with more agility. These lighter shells have large spaces called fontanelles between the shell bones. The shells of leatherback sea turtles are extremely light because they lack scutes and contain many fontanelles.Skin and moltingSnapping turtle tail, Blue Hills Reservation, Massachusetts As mentioned above, the outer layer of the shell is part of the skin; each scute (or plate) on the shell corresponds to a single modified scale. The remainder of the skin is composed of skin with much smaller scales, similar to the skin of other reptiles. Turtles do not molt their skins all at once, as snakes do, but continuously, in small pieces. When kept in aquaria, small sheets of dead skin can be seen in the water (often appearing to be a thin piece of plastic) having been sloughed off when the animal deliberately rubs itself against a piece of wood or stone. Tortoises also shed skin, but a lot of dead skin is allowed to accumulate into thick knobs and plates that provide protection to parts of the body outside the shell.By counting the rings formed by the stack of smaller, older scutes on top of the larger, newer ones, it is possible to estimate the age of a turtle, if one knows how many scutes are produced in a year.[7] This method is not very accurate, partly because growth rate is not constant, but also because some of the scutes eventually fall away from the shell.LimbsTerrestrial tortoises have short, sturdy feet. Tortoises are famous for moving slowly, in part because of their heavy, cumbersome shell, which restricts stride length. The amphibious turtles normally have limbs similar to those of tortoises, except the feet are webbed and often have long claws. These turtles swim using all four feet in a way similar to the dog paddle, with the feet on the left and right side of the body alternately providing thrust. Large turtles tend to swim less than smaller ones, and the very big species, such as alligator snapping turtles, hardly swim at all, preferring to simply walk along the bottom of the river or lake. As well as webbed feet, turtles have very long claws, used to help them clamber onto riverbanks and floating logs, upon which they like to bask. Male turtles tend to have particularly long claws, and these appear to be used to stimulate the female while mating. While most turtles have webbed feet, some, such as the pig-nosed turtle, have true flippers, with the digits being fused into paddles and the claws being relatively small. These species swim in the same way as sea turtles (see below).Sea turtles are almost entirely aquatic and have flippers instead of feet. Sea turtles fly through the water, using the up-and-down motion of the front flippers to generate thrust; the back feet are not used for propulsion, but may be used as rudders for steering. Compared with freshwater turtles, sea turtles have very limited mobility on land, and apart from the dash from the nest to the sea as hatchlings, male sea turtles normally never leave the sea. Females must come back onto land to lay eggs. They move very slowly and laboriously, dragging themselves forwards with their flippers.Ecology and life historySea turtle swimmingAlthough many turtles spend large amounts of their lives underwater, all turtles and tortoises breathe air, and must surface at regular intervals to refill their lungs. They can also spend much of their lives on dry land. Aquatic respiration in Australian freshwater turtles is currently being studied. Some species have large cloacal cavities that are lined with many finger-like projections. These projections, called papillae, have a rich blood supply, and increase the surface area of the cloaca. The turtles can take up dissolved oxygen from the water using these papillae, in much the same way that fish use gills to respire.Turtles lay eggs, like other reptiles, which are slightly soft and leathery. The eggs of the largest species are spherical, while the eggs of the rest are elongated. Their albumen is white and contains a different protein from bird eggs, such that it will not coagulate when cooked. Turtle eggs prepared to eat consist mainly of yolk. In some species, temperature determines whether an egg develops into a male or a female: a higher temperature causes a female, a lower temperature causes a male. Large numbers of eggs are deposited in holes dug into mud or sand. They are then covered and left to incubate by themselves. When the turtles hatch, they squirm their way to the surface and head toward the water. There are no known species in which the mother cares for the young.Sea turtles lay their eggs on dry, sandy beaches. Immature sea turtles are not cared for by the adults. Turtles can take many years to reach breeding age, and in many cases breed every few years rather than annually.Researchers have recently discovered a turtle's organs do not gradually break down or become less efficient over time, unlike most other animals. It was found that the liver, lungs, and kidneys of a centenarian turtle are virtually indistinguishable from those of its immature counterpart. This has inspired genetic researchers to begin examining the turtle genome for longevity genes.[8]Systematics and evolutionSee also: List of Testudines families Odontochelys is the oldest known turtle genusThe first proto-turtles are believed to have existed in the late Triassic Period of the Mesozoic era, about 220 million years ago, and their shell, which has remained a remarkably stable body plan, is thought to have evolved from bony extensions of their backbones and broad ribs that expanded and grew together to form a complete shell that offered protection at every stage of its evolution, even when the bony component of the shell was not complete. This is supported by fossils of the freshwater Odontochelys semitestacea or "half-shelled turtle with teeth", from the late Triassic, which have been found near Guangling[disambiguation needed ] in southwest China. Odontochelys displays a complete bony plastron and an incomplete carapace, similar to an early stage of turtle embryonic development.[9] Prior to this discovery, the earliest-known fossil turtles were terrestrial and had a complete shell, offering no clue to the evolution of this remarkable anatomical feature. By the late Jurassic, turtles had radiated widely, and their fossil history becomes easier to read. "Chelonia" (Testudines) from Ernst Haeckel's Kunstformen der Natur, 1904.Their exact ancestry has been disputed. It was believed they are the only surviving branch of the ancient evolutionary grade Anapsida, which includes groups such as procolophonids, millerettids, protorothyrids, and pareiasaurs. All anapsid skulls lack a temporal opening, while all other extant amniotes have temporal openings (although in mammals the hole has become the zygomatic arch). The millerettids, protorothyrids, and pareiasaurs became extinct in the late Permian period, and the procolophonoids during the Triassic.[10]However, it was later suggested the anapsid-like turtle skull may be due to reversion rather than to anapsid descent. More recent morphological phylogenetic studies with this in mind placed turtles firmly within diapsids, slightly closer to Squamata than to Archosauria.[11] All molecular studies have strongly upheld the placement of turtles within diapsids; some place turtles within Archosauria,[12] or, more commonly, as a sister group to extant archosaurs.[13][14][15][16] Reanalysis of prior phylogenies suggests they classified turtles as anapsids both because they assumed this classification (most of them studying what sort of anapsid turtles are) and because they did not sample fossil and extant taxa broadly enough for constructing the cladogram. Testudines were suggested to have diverged from other diapsids between 200 and 279 million years ago, though the debate is far from settled.[11][13][17]The earliest known fully shelled turtle is the late-Triassic Proganochelys. The genus species already had many advanced turtle traits, and thus probably had many millions of years of preceding turtle evolution and species in its ancestry. It did lack the ability to pull its head into its shell (and it had a long neck), and had a long, spiked tail ending in a club, a body form similar to that of ankylosaurs, resulting from convergent evolution.Turtles are divided into two extant suborders, the Cryptodira and the Pleurodira. The Cryptodira is the larger of the two groups and includes all the marine turtles, the terrestrial tortoises, and many of the freshwater turtles. The Pleurodira are sometimes known as the side-necked turtles, a reference to the way they withdraw their heads into their shells. This smaller group consists primarily of various freshwater turtles. A chart of the two extant Testudine suborders, extinct groups that existed within these two suborders are shown as well.Turtle genera with basal or uncertain phylogenetic positionGenus †Australochelys (Chelonia incertae sedis)Genus †Murrhardtia (Chelonia incertae sedis)Genus †Palaeochersis (Chelonia incertae sedis)Genus †Chinlechelys (Proganochelydia or basal Testudines)Genus †Chelycarapookus (Testudines incertae sedis)Genus †Chitracephalus (Testudines incertae sedis)Genus †Neusticemys (Testudines incertae sedis)Genus †Scutemys (Testudines incertae sedis)Suborder †ProganochelydiaGenus †Odontochelys (tentatively placed here)Genus †ProganochelysFossil of Proganochelys quenstedti, it is one of the oldest true turtles presently known.

Precisely how these alternative names are used, if at all, depends on the type of English being used. British English normally describes these reptiles as turtles if they live in the sea; terrapins if they live in fresh or brackish water; or tortoises if they live on land. However, there are exceptions to this where American or Australian common names are in wide use, as with the Fly River turtle.American English tends to use the word turtle as a general term for all species. "Tortoise" is used for most land-dwelling species, including the family Testudinidae and box tortoises. Oceanic species are usually referred to as sea turtles. The name "terrapin" is typically reserved only for the brackish water diamondback terrapin, Malaclemys terrapin; the word terrapin being derived from the Algonquian word for this animal.[18]Australian English uses turtle for both the marine and freshwater species, but tortoise for the terrestrial species.[18]To avoid confusion, the word "chelonian" is popular among veterinarians, scientists, and conservationists working with these animals as a catch-all name for any member of the superorder Chelonia, which includes all turtles, tortoises and terrapins living and extinct, as well as their immediate ancestors. It is based on the Ancient Greek word χελώνη, chelōnē; Modern Greek χελώνα, chelōna; meaning turtle/tortoise.Some languages do not have this problem, as all of these are referred to by the same name. For example, in Spanish, the word "tortuga" is used for turtles, tortoises and terrapins, though the type they belong to is usually specified and added to the name, as "marina" for sea turtles, "de río", for freshwater species and "terrestre" for tortoises.DistributionSeven species of marine turtles are found worldwide. Of these, five have been recorded in Europe.[19] Fossil recordNeonate sized turtle fossils have been documented in the scientific literature.[20] GenomicsTurtles possess diverse chromosome numbers (2N = 28-66) and a myriad of chromosomal rearrangements have occurred during evolution.[21] As petsRed eared slider basking on a floating platform under a sun lamp Turtles, particularly small terrestrial and freshwater turtles, are commonly kept as pets. Among the most popular are Russian tortoises, spur-thighed tortoises, and red-eared sliders.[22]In the United States, due to the ease of contracting salmonellosis through casual contact with turtles, the U.S. Food and Drug Administration (FDA) established a regulation in 1975 to discontinue the sale of turtles under 4 inches.[23] It is illegal in every state in the U.S. for anyone to sell any turtles under 4 inches (10 cm) long. Many stores and flea markets still sell small turtles due to a loophole in the FDA regulation which allows turtles under 4 inches to be sold for educational purposes.[24][25]Some states have other laws and regulations regarding possession of red-eared sliders as pets because they are looked upon as invasive species or pests where they are not native, but have been introduced through the pet trade. As of July 1, 2007, it is illegal in Florida to sell any wild type red-eared slider. Unusual color varieties such as albino and pastel red-eared sliders, which are derived from captive breeding, are still allowed for sale.[26]As food, traditional medicine, and cosmeticsThe window of a restaurant serving guilinggao, decorated with a 龜 ("turtle") character. The flesh of turtles, calipash or calipee, was, and still is, considered a delicacy in a number of cultures.[3] Turtle soup has been a prized dish in Anglo-American cuisine,[27] and still remains so in some parts of Asia.[which?] Gopher tortoise stew was popular with some groups in Florida.[28]Turtles remain a part of the traditional diet on the island of Grand Cayman, so much so that when wild stocks became depleted, a turtle farm was established specifically to raise sea turtles for their meat. The farm also releases specimens to the wild as part of an effort to repopulate the Caribbean Sea.[29]Fat from turtles is also used in the Caribbean and in Mexico as a main ingredient in cosmetics, marketed under its Spanish name crema de tortuga.[30] Turtle plastrons among other plants and animals parts are used in traditional Chinese medicines. (Other items in the image are dried lingzhi, snake, luo han guo, and ginseng).Turtle plastrons (the part of the shell that covers a tortoise from the bottom) are widely used in traditional Chinese medicine; according to statistics, Taiwan imports hundreds of tons of plastrons every year.[31] A popular medicinal preparation based on powdered turtle plastron (and a variety of herbs) is the guilinggao jelly;[32][33] these days, though, it is typically made with only herbal ingredients.Conservation statusIn February 2011, the IUCN/SSC Tortoise and Freshwater Turtle Specialist Group published a report about the top 25 species of turtles most likely to become extinct, with a further 40 species at very high risk of becoming extinct. This list excludes sea turtles, however both the leatherback and the Kemp's ridley would make the top 25 list. The report is due to be updated in four years time allowing to follow the evolution of the list. Between 48 to 54% of all 328 of their species considered threatened, turtles and tortoises are at a much higher risk of extinction than many other vertebrates. Of the 263 species of freshwater and terrestrial turtles, 117 species are considered Threatened, 73 are either Endangered or Critically Endangered and 1 is Extinct. Of the 58 species belonging to the Testudinidae family, 33 species are Threatened, 18 are either Endangered or Critically Endangered, 1 is Extinct in the wild and 7 species are Extinct. 71% of all tortoise species are either gone or almost gone. Asian species are the most endangered, closely followed by the five endemic species from Madagascar. Turtles face many threats, including habitat destruction, harvesting for consumption and pet trade. The high extinction risk for Asian species is primarily due to the long-term unsustainable exploitation of turtles and tortoises for consumption and traditional Chinese medicine, and to a lesser extent for the international pet trade.[34] Efforts have been made by Chinese entrepreneurs to satisfy increasing demand for turtle meat as gourmet food and traditional medicine with farmed turtles, instead of wild-caught ones; according to a study published in 2007, over a thousand turtle farms operated in China.[35][36] Turtle farms in Oklahoma and Louisiana raise turtles for export to China as well.[36] Turtles on tree branch over a lake in New Jersey.Nonetheless, wild turtles continue to be caught and sent to market in large number (as well as to turtle farms, to be used as breeding stock[35]), resulting in a situation described by conservationists as "the Asian turtle crisis".[37] In the words of the biologist George Amato, "the amount and the volume of captured turtles... vacuumed up entire species from areas in Southeast Asia", even as biologists still did not know how many distinct turtle species live in the region.[38] About 75% of Asia's 90 tortoise and freshwater turtle species are estimated to have become threatened.[36]Harvesting wild turtles is legal in a number of states in the USA.[36] In one of these states, Florida, just a single seafood company in Fort Lauderdale was reported in 2008 as buying about 5,000 pounds of softshell turtles a week. The harvesters (hunters) are paid about $2 a pound; some manage to catch as many as 30-40 turtles (500 pounds) on a good day. Some of the catch gets to the local restaurants, while most of it is exported to Asia. The Florida Fish and Wildlife Conservation Commission estimated in 2008 that around 3,000 pounds of softshell turtles were exported each week via Tampa International Airport.[39]Nonetheless, the great majority of turtles exported from the USA are farm raised. According to one estimate by the World Chelonian Trust, about 97% of 31.8 million animals harvested in the U.S. over a three-year period (November 4, 2002 - November 26, 2005) were exported.[36][40] It has been estimated (presumably, over the same 2002-2005 period) that about 47% of the US turtle exports go to People's Republic of China (predominantly to Hong Kong), another 20% to Taiwan, and 11% to Mexico.
