<s>[INST] I have been taking saw palmetto for prostate issues and male pattern baldness for many years - works great. I am 69 years old now. Now I have sexual problems - lack of erection and weak orgassium and insomnia. Are these a side effects, similar to propecia, side effects from saw palmetto?. [/INST] Hi, Saw palmetto is a herbal medicine and it does not get any proven evidence for its efficacy. I suggest you consult a urologist and get evaluated for your problem rather than going behind wonder drugs. Hope I have answered your query. Let me know if I can assist you further.
