Ashwaghanda mg to tablespoons?

I have a student of mine who is gradually loosing the nerves in her feet (she wears braces to walk) and Ive introduced ashwaghanda to her. She bought capsules with 350mg in them. How many of those would equal 3 tablespoons of ashwaghanda?

Also, I've recommened that she join the forum and that she look into the Incurables Program, so hopefully she will.
