It has been used topically in Persian medicine and compared other treatments it is easily available and low cost. In clinical practice patients applying chickpea oil have expressed their satisfaction. Given the lack of valid scientific studies, this randomised controlled trial was conducted to evaluate the effect of topical chickpea oil on knees affected by osteoarthritis.

The groups were compared at the end of treatment. Results WOMAC scores showed significant reduction in pain, stiffness, and difficuly in activity in the chickpea oil group compared wih the piroxicam or paraffin group(p  Conclusions The results of this study demonstrated that chickpea oil could be effective in relieving pain, reducing motion stiffness, and increasing activity in osteoarthritis patients.
