Less or reduced synovial fluid in the space between the joints cause less to no lubrication and lead to bones rubbing against each other causing continuous pain. Sandhi Sudha on application penetrates the layers of skin through the outer tissues and reaches the joint space restoring the lubrication and warmth between the joint. The swollen inflammatory tissues around the joint get immediate relief from the application of Sandhi Sudha reducing the pain coming from these tissues. Increased blood flow in the veins around the joint stimulate the synovial membranes for better fluid production thus providing effective lubrication between joints. It also regenerates the damaged tissue and treats the injured parts of that area.
