Panchakarma :

Five treatment to clean the body of the toxic substances. Panchakarma is a Sanskrit word that means “five actions” or “five treatments.” This is a process used to clean the body of toxic materials left by disease and poor nutrition. Ayurveda says that imbalanced doshas create waste matter. This waste matter is called Ama in Ayurveda. Ama is a foul-smelling, sticky, noxious substance that needs to be evacuated from the body as thoroughly as possible.

Panchakarma will stick out the excess doshas (or imbalances in the dosha) along with the sticky Ama out of your system by means of the body waste evacuation channels such as sweat glands, urinary tract, intestines, etc. panchakarma is, thus, a balancing operation. It involves daily massages and oil baths and is extremely pleasant experience. Ayurveda recommends Panchakarma as a seasonal treatment for toning your mind body system.
