Is there any alternative medicine for mental wellness as there is for general aches and pains?

Yes: Mindfulness meditation. The good news is this has begun to cross over where psychologists now also teach and practice it. Of course, there are other forms such as acupuncture, massage therapy, etc. That may fall into this category.

Many strategies: can be applied to maintain or improve mental wellness short of medication. These can include: talk therapy, relaxation activities, meditation, yoga, herbal remedies, and more. Find an open-minded physician who specializes in areas such as holistic medicine, alternative medicine, integrative medicine, wellness, anti aging, or preventative medicine. Explore your options with them. Best wishes
