Note: Oleander is also available in patent medicine form and their is a new supplement that features oleander along with chaparral and graviola from Alpha-Omega labs. Or, you can make your own oleander extract at home if you have access to oleander plants that have not been contaminated by pesticides (and you follow directions carefully).
