From what I know,karanj is traditionally used for minor wounds and cuts in Ayurveda. Oil from the karanj tree is believed to have skin-supporting properties that may help keep the affected area clean and promote healing. In some traditional households, paste made from the karanj plant leaves is applied externally on small cuts or rough skin. The karanja tree has been used for generations because of its natural healing value. I personally find it interesting how many herbal remedies still rely on such plants. That said, for deep wounds or serious infections, proper medical treatment is always important. Herbal support like karanj may be helpful only for small everyday skin concerns.
