It has been estimated that in developed countries such as United States, plants drugs comprise
up to 25% of the total drugs, while in fast developing countries such as China and India, it
comprise up to 80%. It is expected that there are 250,000 to 500,000 species of plants on Earth.
Out of these small percentages (1 to 10%) are used as foods and medicine by both humans and
animal. It is possible that rest of plant may be used for foods and medicinal purposes.
Hence, it has turn out to be very important to review on herbal medicinewhich will play
important role in research on plant to find their possible medicinal importance.
Herbal formulations means a dosage form consisting of one or more herbs or processed herbs
in specified quantities to provide specific nutritional, cosmetic benefits meant for use to
diagnose, treat, mitigate diseases of human beings or animals, alter the structure or physiology
of human beings or animals. Herbal formulations contain an active substance or herbal
substance or herbal preparation or herbal substance in combination with one or more herbal
preparations. Herbal formulations are obtained by subjecting herbal substances to treatments
such as extraction, distillation, expression, fractionation, purification, concentration or
fermentation include comminuted or powdered. Whole, fragmented or cut plants, plants parts,
algae, fungi, lichen in an unprocessed, usually dried form but sometimes fresh were used in the
preparations of herbal formulations. Herbal substances are precisely defined by the plant part
used and the botanical name according to the binomial system (genus, species, variety and

It follows from the data studied that information on the content of chemical elements in animal hair, depending on the presence of melanin, should be related to the concentration of this pigment, before judging the effect of environmental factors on their content. For a long time it was assumed that, the entry of mineral substances into the hair occurs from the blood capillaries, which are supplied to the hair follicle bulbs and the epithelial layers of the skin. There have been attempts to establish a positive correlation between the content of mineral and organic substances in the blood. When comparing the reaction of blood plasma and rat hair to a change in the composition of food, it was found that plasma quickly responds to changes in the content of magnesium and calcium in the diet, slowly - to the content of phosphorus and does not react at all to changes in the level of sodium and calcium (this is explained by a clear homeostatic regulation of the content of these elements in the blood). At the same time, the hair reacts quickly to changes in sodium content, slowly to calcium, magnesium, phosphorus, and very slowly to changes in potassium concentration.
