My husband has Parkinson’s for last 4 years… no medications as of now. We are trying alternate therapy like Qi gong. What can we do to reduce the tremors in his arms, hands and legs. He is able to do all his work himself. Tremors are mild started with his left hand progressed to left leg after a year and now after 2 years has come to right arm and little bit to his right leg. What bothers him most is toes curling in left foot. Thanks
