Confused about oleander.

I have heard that Oleander can get rid of an allergy related rash (have gotten rid of the allergy source but not the rash). However, some sites say Oleander is toxic and talk about taking charcoal with it. Then again, at a health food store someone told me people were buying Oleander from her to give massages.

What is the big deal about oleander, and how can one use it safely? Can I apply it directly to the rash, for example? One person on CZ said a couple of drops under his tongue got rid of dizziness. Sometimes I have allergy related dizziness. Do you recommend this approach? Tweet
