What is caffeine?

Caffeine is a bitter white crystalline xanthine that acts as a psychoactive stimulant drug and a mild diuretic (speeds up urine production) in humans and other animals. Caffeine was discovered by a German chemist, Friedrich Ferdinand Runge, in 1819. He coined the term "kaffein", a chemical compound in coffee, which in English became caffeine. Caffeine is also called guaranine when found in guarana, mateine when found in mate, and theine when found in tea; all of these names are synonyms for the same chemical compound. Caffeine is found in varying quantities in the beans, leaves, and fruit of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the beans of the coffee plant and the leaves of the tea bush, as well as from various foods and drinks containing products derived from the kola nut. Other sources include yerba mate, guarana berries, and the Yaupon Holly. In humans, caffeine is a central nervous system (CNS) stimulant, having the effect of temporarily warding off drowsiness and restoring alertness. Beverages containing caffeine, such as coffee, tea, soft drinks and energy drinks enjoy great popularity. Caffeine is the world's most widely consumed psychoactive substance, but unlike most others, it is legal and unregulated in nearly all jurisdictions. In North America, 90% of adults consume caffeine daily. The U.S. Food and Drug Administration lists caffeine as a "Multiple Purpose Generally Recognized as Safe Food Substance.One 2008 study suggested that women consuming 200 milligrams or more of caffeine per day had about twice the miscarriage risk as women who had none, while another 2008 study found no link between miscarriage and caffeine consumption. Please see the Related Questions and the Sources and Related Links below. Caffeine is a naturally occurring white bitter alkaloid found in the seeds and other parts of plants, particularly coffee. It acts as a natural insecticide for the plants, helping to control and even kill some of the insects that would feed on the plants, and and the same time it acts as a reward mechanism for insects that pollinate the plants. In humans it acts as central nervous system (CNS) stimulant.

What is the history of caffeine?

Humans have consumed caffeine since the Stone Age. Early peoples found that chewing the seeds, bark, or leaves of certain plants had the effects of easing fatigue, stimulating awareness, and elevating one's mood. Only much later was it found that the effect of caffeine was increased by steeping such plants in hot water. Many cultures have legends that attribute the discovery of such plants to people living many thousands of years ago. According to one popular Chinese legend, the Emperor of China Shennong, reputed to have reigned in about 3000 BC, accidentally discovered that when some leaves fell into boiling water, a fragrant and restorative drink resulted. Shennong is also mentioned in Lu Yu's Cha Jing , a famous early work on the subject of tea. The history of coffee has been recorded as far back as the ninth century. During that time, coffee beans were available only in their native habitat, Ethiopia. A popular legend traces its discovery to a goatherder named Kaldi, who apparently observed goats that became elated and sleepless at night after grazing on coffee shrubs and, upon trying the berries that the goats had been eating, experienced the same vitality. The earliest literary mention of coffee may be a reference to Bunchum in the works of the 9th-century Persian physician al-Razi. In 1587, Malaye Jaziri compiled a work tracing the history and legal controversies of coffee, entitled "Undat al safwa fi hill al-qahwa". In this work, Jaziri recorded that one Sheikh, Jamal-al-Din al-Dhabhani, mufti of Aden, was the first to adopt the use of coffee in 1454, and that in the 15th century the Sufis of Yemen routinely used coffee to stay awake during prayers. Towards the close of the 16th century, the use of coffee was recorded by a European resident in Egypt, and about this time it came into general use in the Near East. The appreciation of coffee as a beverage in Europe, where it was first known as "Arabian wine," dates from the 17th century. A legend states that, after the Ottoman Turks retreated from the walls of Vienna after losing a battle for the city, many sacks of coffee beans were found among their baggage. Europeans did not know what to do with all the coffee beans, being unfamiliar with them. So Franz George Kolschitzky, a Pole who had actually worked for the Turks, offered to take them. He subsequently taught the Viennese how to make coffee, and the first coffee house in the Western world was opened in Vienna, thus starting a long tradition of coffee appreciation. In Britain, the first coffee houses were opened in London in 1652, at St Michael's Alley, Cornhill. They soon became popular throughout Western Europe, and played a significant role in social relations in the 17th and 18th centuries. The kola nut, like the coffee berry and tea leaf, appears to have ancient origins. It is chewed in many West African cultures, individually or in a social setting, to restore vitality and ease hunger pangs. In 1911, kola became the focus of one of the earliest documented health scares when the US government seized 40 barrels and 20 kegs of Coca-Cola syrup in Chattanooga, Tennessee, alleging that the caffeine in its drink was "injurious to health". On March 13, 1911, the government initiated United States v. Forty Barrels and Twenty Kegs of Coca-Cola , hoping to force Coca-Cola to remove caffeine from its formula by making claims, such as that the excessive use of Coca-Cola at one girls' school led to "wild nocturnal freaks, violations of college rules and female proprieties, and even immoralities." Although the judge ruled in favor of Coca-Cola, two bills were introduced to the U.S. House of Representatives in 1912 to amend the Pure Food and Drug Act, adding caffeine to the list of "habit-forming" and "deleterious" substances, which must be listed on a product's label. The earliest evidence of cocoa bean use comes from residue found in an ancient Mayan pot dated to 600 BC. In the New World, chocolate was consumed in a bitter and spicy drink called xocoatl , often seasoned with vanilla, Chile pepper, and achiote. Xocoatl was believed to fight fatigue, a belief that is probably attributable to the theobromine and caffeine content. Chocolate was an important luxury good throughout pre-Columbian Mesoamerica, and cocoa beans were often used as currency. Xocoatl was introduced to Europe by the Spaniards and became a popular beverage by 1700. They also introduced the cacao tree into the West Indies and the Philippines. It was used in alchemical processes, where it was known as Black Bean. The leaves and stems of the Yaupon Holly ( Ilex vomitoria ) were used by Native Americans to brew a tea called Asi or the "black drink". Archaeologists have found evidence of this use stretch back far into antiquity, possibly dating to Late Archaic times. Source: Wikipedia

Can dogs have caffeine?

Dogs can have caffeine in moderate amounts. Moderate is not a specific answer, therefore, the answer is: 150 milligram (mg) of coffee maximum every 24 hours. However, because dogs come in different weights, the dogs weight must be divided by 2.2 kilogram (one pound) to reach the correct answer. Example: my dog a Boxer weighs 80 pounds. 80 divided by 2.2= 36.36 milligram. I let him have 3/4 cup with creamer daily which is alright. Example: A Pekingese weighs 10 pound. Ten pound divided by 2.2 kilogram = less than 5 mg of coffee daily for this smaller dog. The above assumes your dog has no underlying illness i.e. cardiac problems; poor kidney function etc. Ask your vet for a definitive answer as I am not a veterinarian.
