When our joints undergo wear and tear constant pain sets in. Over a period of time as our joints age the NATURAL lubrication is lost. Due to constant friction inflammation sets in causing bad pain.
Ayurvedic oils like Joint Boost Oil have herbs like Parsarini, Erandmool, Rasna, Piplamool, Til, Lavang etc which when massaged help heat the affected area and relieve pain to an extent.
Including natural lubricants in diet (like GHEE) backed with regular exercise (to strengthen muscles) will definitely improve Joint health.
