Holy Basil on Amazon.com Holy Basil on iHerb.com (first-time customers get $5-10 off of their order) I just read about this supplement and went out and purchased it. It supposed to lower cortisol levels which would help with sleeping. Sometimes due to poor sleeping, I feel like I have extra cortisol running through my body, especially when I wake up in the middle of the night. Anyone try Holy Basil? Thanks.
