I read in a research paper that certain botanicals such as stinging nettle, reishi mushroom, and curcumin have anti-glial properties. Does anyone know of others that also have anti-glial results?

I am very interested in trying curcumin but know that it is not well absorbed by the body, can be expensive, and there are many inferior brands on the market. Can anyone recommend a good brand(s)?

Thanks for your help.
