Official allergy treatment similar to mine is called sublingual immunotherapy,
but allergen is put under the tongue instead.

Thank you I will try that...but I got a henna tattoo in Cancun, Mexico on my back, and within 1/2 hr my back was all swollen up around the tattoo, it looked like I was branded with a big aerosmith logo, instead of the henna. So is hair henna different that henna for tattoos? Or maybe just poor quality in Mexico? Your thoughts?
P.S. I should mention that I have used henna myself and that I am a very allergic type.
Natural henna will not harm your skin. There are some henna preparations that have additives so that there are more colors available thant red. In the Middle East, where henna is used regularly, it is considerate healthy for the skin and hair, and is often used for its healthful qualities alone. Just make sure you get the pure product
