Cosmetic potential of herbal extracts

Abstract

Cosmetology, the science of alteration of appearance, has been practiced since primordial times. In India, the concept of using herbs for beautification finds its origin in traditional medicine literature like Ayurveda. The cosmetic preparations were used for the purpose of worship and sensual enjoyment. Moreover, since centuries, the herbal extracts, as a whole or part thereof, have been used for various ailments of the skin, hair and for overall appearance. The market research shows upward trend in the herbal trade with the herbal cosmetic industry playing a major role in fuelling this worldwide demand for herbals. The recent interest of consumers in herbal cosmetics has been stimulated by the decline of faith in modern cosmetics, the belief that plant remedies were natural and thereby superior to man-made synthetic cosmetics, and the reference to successful historical use by different cultures. These reasons have contributed to the increased acceptance as well as manufacture of herbal cosmetics. Many herbs have been scientifically evaluated for their cosmetic potential. Some traditional plants like Trigonella foenum-graecum Linn., Azadirachta indica A. Juss., Mimosa tenuiflora Benth., Aloe vera Linn., etc. need special mention. The great void remains though for a systematic, thorough review of scientific data that provides a basis for the use of specific herbs and their efficacy as cosmetics. Similarly, there is a lack of scientific review of phytochemicals that are used in cosmetic preparations. This review attempts to fill-up this gap and emphasizes the need for safety evaluation of herbal cosmetics.
