Henna is an old tradition in Turkish Culture. It is an important part of the weddings & special ceremonies. The henna plant is one of the oldest cosmetics ever used and is extremely safe. Natural henna, when applied to the skin rarely causes any adverse reactions, if you are concerned you should do a small patch test first. Natural henna is safe even for use on children as it contains no dangerous chemical dyes or harsh additives.
Fresh henna powder smells like fresh cut hay or spinach and is an earthy green or khaki colour. If the powder is bright green in colour a chemical dye has been added. If the powder is brown and has little or no scent, it is likely the product is stale and too old to yield a good colour for mehndi or henna body painting.
