That's good information to know, I had not heard of Giloy. While reading your post in my mind I was thinking if I could get for my hubby, but then your last line that it's not suitable for autoimmune disappoints. His is an Autoimmune condition Myasthenia Gravis, and I keep him on natural therapies to improve his health.
Ya, it will be not a good fit for him. What about Aloe vera ?
