Herbs to Enhance Immunity in Winter Months

Immunity Lehams Rasayana Seasonal Changes

Rasayana is a special therapy Ayurveda uses for rejuvenation of the body, mind and spirit


It’s one of the eight branches of classical Ayurveda, specializing in nutrition, immunology and care for the sick and elderly. One of the ways Rasayana enhances immunity is by the use of Lehams (Lehams are sometimes also called Rasayanas). Lehams are herbal jams made from fresh fruit and herbs combined with honey, ghee, sesame and sugar. Delicious as well as nutritious!         

Lehams rejuvenate the body at the cellular level and enhances ojas (strength and immunity) through its nutrient-dense ingredients; while at the same time Lehams promote healthy digestion and a strong metabolism. These special herbal products are known for three actions that improve longevity and quality of life:

  1. Nutrient-dense ingredients
  2. Boost for digestion and metabolism
  3. Increased lymph circulation and cellular activity

Most Ayurvedic practitioners will recommend a purification process before Rasayana therapy is recommended. The purification process includes dietary cleansing with foods and spices based on your imbalance and prepares the body for rejuvenation. Even people who are weak or sick are advised to first improve digestion first before taking a Leham.

The best Rasayana therapy regimens are overseen by an Ayurvedic practitioner who can fully understand your state of health and offer you the best care!       


Two Rasayana Herbs

Haritaki and Amalaki are two key herbs included with most Rasayana therapies. They are considered like nectar and have very similar actions (except Haritaki is warming and Amalaki is cooling). Both Lehams move impurities through and out of the body, improve bodily functions and balance metabolism.
