http://en.wikipedia.org/wiki/Henna
The United States Food and Drug Administration has not approved henna for direct application to the skin. It is unconditionally approved as a hair dye, and can only be imported for that purpose.[10][11] Henna imported into the USA which appears to be for use as body art is subject to seizure,[citation needed] though prosecution is rare. The fast black stains of "black henna" are not made with henna, but are from p-phenylenediamine. This can cause severe allergic reactions and permanent scarring. Natural henna stains only a rich red brown. P-phenylenediamine can stain skin black quickly, but the FDA specifically forbids PPD to be used for that purpose. |
