Uses & Effectiveness

Insufficient Evidence to Rate Effectiveness for...

Early research suggests that taking a combination product containing ash bark and Smilax glabra root (Rebixiao granules) by mouth reduces levels uric acid in the blood better than the drug diclofenac in people with gout.
  • Fever.
  • Arthritis.
  • Bladder problems.
  • Constipation.
  • Increasing urine production to relieve water retention (as a diuretic).

More evidence is needed to rate the effectiveness of ash for these uses.

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
