Arthritis: . I started using manchurian mushroom tea (aka kombucha tea). . (real homemade), my sister turned me on to over 20 yrs. Ago. Works very well for shoulder arthritis. It worked very good, but as I'm older I need a larger dose, approximately 11 ounces. To start with u only need 4 ounces. It's not working as good on me anymore. I'm 64. Cold weather doesn't help. I'm in Colorado.
