Traditional Ayurvedic Uses:
The root of this plant is a powerful Rasayana (longevity enhancer). It is good for the kidneys, especially the nephron cells which are damaged by long-term hyperglycemia (diabetes). And it pacifies two of the main laws of physiology (Vata and Kapha).
Punarnava enhances the quality of 6 of the 7 categories of bodily tissues, including nutrient plasma (Rasa Dhatu), blood (Rakta Dhatu), muscle (Mamsa Dhatu), fat (Meda Dhatu), bone marrow and nerves (Majja Dhatu), and reproductive fluids (Shukra Dhatu).
HEART: Fluid congestion, cardiac edema, general edema from heart function deficiency. Difficult breathing from this congestion in the chest is eased. By clearing the excess of avalambhaka and kledhaka kapha from the chest and stomach it opens the channels- especially for rasa and rakta, the circulatory fluids, to flow unimpeded.
KIDNEYS: Any symptoms of nephritis or impaired urinary function. Used in bladder infections and systemic edema. Superb herb for drying excess fluids, swelling, edema and congestion from excess kapha. Specifically useful in ascites, congestive heart conditions, arthritic swellings with pitting and coldness.2
GIT: Increases the digestive fire and is useful in a sluggish digestive system. In small doses it is a mild laxative. Also traditionally used for treating the kapha type of anemia.3
ARTHRITIS: In swollen joints with fluid retention, pitting with kapha imbalance Punarnava can effectively clear the excess fluid.
