Garlic is known to be helpful in treating many health conditions. It has been clinically supported that garlic can be used to treat diabetes, colds, and rheumatoid arthritis, just to name a few. It strengthens the immune system and has anti-inflammatory properties. Plus, it can reverse the effects of nephrotoxicity, a side effect of drugs commonly prescribed for arthritis treatment.
A study in 1999 observed the effects of garlic on 30 patients who suffered from rheumatoid arthritis. They found that the garlic improved many of their symptoms with no side effects.
