Kamya Rasayana and Naimittika Rasayana are two general kinds of Rasayana Therapy. These two branches are further divided into other therapies. The Kamya Rasayana helps in promoting normal health by boosting energy. Naimittika Rasayana is for warding off certain diseases. Some foods also act as Rasayana such as ghee, lemon, ginger, cumin, dates, figs, almonds, lassi, green gram and seasonal fruits. The detoxification of the body or Panchakarma is an important therapy carried out before Rasayana Therapy. Only a clean and unclogged body can absorb, circulate and react to the medicines and therapies in a positive way.
