Thanks for the information about Black Henna and the concerns expressed about it. I've done Henna tattoos, hair dying and also used it in various other artistic ways in the past. I know about Black Henna and the dangers involved in using it and wouldn't go near the stuff. I'm not into hardcore body altering. When using any dye products, even when sold in popular stores or pharmacies, it is always advisable to do a skin test first. Different people react differently to various products and the chemicals contained in them. Some even react to certain dye's used in clothing and textiles.
I used the image of the woman because my friend is a woman and wanted something similar to the tattoo done in the image, except bigger and wrapping around her breasts and top half of her body. I happen to think it is a beautiful and artist picture depicting the female form and my apologies to those for any offense given by it.
In the meantime I have found a licensed supplier in California that will ship Henna kits/products to me at a good price
