After a long absence. I've just started to make it again and was delighted to read that kombucha tea allegedly does this
Kombucha contains glucosamines, a strong preventive and treatment all forms of arthritis. Glucosamines increase synovial hyaluronic acid production. Hyaluronic acid functions physiologically to aid preservation of cartilage structure and prevent arthritic pain, with relief comparable to NSAIDs and advantage over glucocorticoids. Hyaluronic acid enables connective tissue to bind moisture thousands of times its weight and maintains tissue structure, moisture, lubrication and flexibility and lessens free radical damage, while associated collagen retards and reduces wrinkles.
