Examples of crude drugs used in Kampo preparations include glycyrrhiza (licorice ), rhubarb, and ginseng.
The crude drugs can be identified on the basis of their morphological, histological, and chemical characters called drug evaluation.The different techniques involved in standardization of crude drugs areMorphological and organoleptic evaluationIt refers to the evaluation of drugs by color, odor, taste, size, shape and special features like texture. This method allows more detailed examination of a drug and their identification by their known histological characters. Microscope by the virtue of its property to magnify, permits minute sections under study to enlarge so that, leaf constants, stomatal index, palisade ratio can be determined.Physical evaluationThese are rarely constant for crude drugs, but may help in evaluation with reference to moisture content, specific gravity, density, optic rotation, refractive index, melting point, viscosity, solubility etc.Chemical evaluationIt compromises of different chemical test and assays. The isolation, purification and identification of active constituents are the methods of evaluation. Quantitative chemical test such as acid value, saponification value etc are also covered under these techniques.Biological evaluationWhen the estimation of potency of crude drug or its preparations are done by means of measuring its effect on living organisms like bacteria, fungal growth, or animal tissue, it is known as biological effect of the drug, compared to the standard drug.By these methods a crude drug can be assessed and further clinical trial can be recommended
Crude botanical drugs containing mucilages are employed because the possess demulcent attributes. Marshmallow, slippery elm and aloe vera are examples of mucilages.
the Melting point depends on different types of Crude oil.. Crude oils are of different types ..so there is no specific Boiling point
crude intergrated hardened
Placement evaluation
There are four types of drugs available to treat dyslipidemia. The four types of drugs are the statins , the fibrates, HMG-COA, and bile acid binding resins.
3 Types of Chloride Salts are found in crude oil: Calcium, Sodium and Magnesium Chlorides
Placement evaluation
Crude oil has oxygen, carbon dioxide and gastro hemus in it.
No, but they're both types of fossil fuels.
