May Relieve Depression
As reported by Life Extension Magazine, muira puama has a long history of use by Amazonian people to treat various maladies. They use it to relieve stress, among other things. A 2008 study by Brazilian researchers comparing muira puama to the antidepressant drug imipramine demonstrated them to be equally effective in relieving the symptoms of depression. Researchers have also found little adverse effects from using muira puama, according to Life Extension. Check with a licensed therapist or your doctor before taking muira puama to relieve depression.
Can Improve Memory
Life Extension also reports that muira puama might help improve memory among older people. In a 2004 study conducted by Brazilian researchers, aging rats treated with muira puama performed as well as adult mice. Researchers theorize muira puama may be effective due to inhibiting acetylcholinesterase. Acetylcholinesterase is an that enzyme breaks down the important neurotransmitter acetylcholine, necessary for memory and cognition. By protecting acetylcholine, muira puama might have therapeutic value for memory or cognition-impaired people. If you're on an acetylcholinesterase inhibitor such as donepezil, consult a physician before taking any natural remedy such as muira puama.
