Want to quickly give my experience trialing holy basil. Holy basil had helped a friend of mine closeby with her CFS symptoms, so I figured I'd try it out. What I took was Holy Basil Force from New Chapter which is holy basil extract. My friend who experienced positive results took a milder form in the form of tea bags. So a couple hours after my first dose of it, I felt a big difference in that my mild anxiety was much better, and I was also feeling a pretty severe sore throat, more severe than my chronic mild sore throat. I also had a big increase in energy and stamina. So this lasted about a week, and roughly a week after starting it, I had a pretty big crash - poor strength, sleeping all the time. I stopped for a while and then tried it again - that time it again caused a sore throat but then I felt coldness in my hands and feet which is very unusual for me. So, either the holy basil itself does not agree with me, or that I was taking it in extract form instead of a gentler form caused the problems. So just in case anyone is thinking about trying holy basil, that is my experience!
