I never tried Ashwagandha, but I know the herb is an adaptogen (similar to Royal Maca), and is known as a mood stabilizer as well as enhancing the immune system. Adaptogen herbs help the body "adapt" to physiological and psychological stresses.
The reason I went with Royal Maca is because it specifically benefits women who have had hysterectomies. It's worked for me in various ways such as:
-- heightened libido
-- increase in vaginal lubrication
-- more energy (adrenal fatigue isn't as prominent)
-- hormonal balance (no more night sweats)
-- improved mood (I'm not as weepy or cranky during my PMS cycle)
Before starting any regime, please make sure you chat with your doctor to see if this herb would be benefical for you. I know that Royal Maca is NOT recommended for women who use estrogen supplements such as:
-- estrogen suppositories (although my doctor prescribed vaginal estrogen for dryness which I stopped using since Royal Maca took care of the problem)
-- bio-identical estrogen
-- phytoestrogenic herbs such as black cohost, isoflavones of soy and certain Chinese herbs)
-- adaptogenic herbs (except as directed by your doctor)
I would NOT take both herbs at the same time since it is not recommended to combine adaptogenic herbs (unless it is prescribed by your doctor).
Good luck, and let me know which herb you choose.
