Henna is a small tree/shrub which is found in Southern Asia, Northern Africa and Northern Australasia.
The leaves of the Henna Plant are dried, milled and sifted to create a powder which is mixed with liquids such as water and lemon juice to create a Henna Paste.
When henna is first removed from the skin it has an orange stain and darkens over the next 24-48 hours to a maroon/brown color.
Soles of the feet and palms have the thickest layer of skin which take up the most Lawson therefore the hands and feet will have the darkest and most long-lasting stains.
Natural Henna stains only brown to maroon color. Products sold as "black henna" or "neutral henna" DO NOT contain henna, but instead are made from other plants or from other substances all together.
PPD (Para-phenylendiamine) which is found in most "black henna" can cause severe allergic reactions, with blistering intense itching, permanent scarring and permanent chemical sensitivities.
Henna has been practiced for centuries in Northern Africa, Southern Asia, Middle East, and Europe. It has been used across all religions for various reasons such as marriage, pregnancy, circumcisions, holidays and much more. Certain designs have different meanings for different cultures. Some find good health, fertility, wisdom, spiritual protection, or luck in henna designs. For weddings some men even take part in henna, masculine designs in certain cultures are more basic and small compared to a feminine design where it can cover her entire hands, arms, feet and legs.
