Varun – (Crataeva nurvala) – In Ayurveda, the bark of kidney damage.



Crataeva (Crataeva nurvala)


In Ayurveda, the bark of the Crataeva has been traditionally used to heal kidney stones for more than 3,000 years. Findings of several studies undertaken by contemporary scientists have authenticated that the herb neutralizes the enzyme called glycolate oxidase and this particular effect of the herb lessens the production of oxalates by the body. It may be mentioned here that the oxalates combine with calcium to develop into kidney stones. Another chemical enclosed by Crataeva, lupeol, helps to lower the intensity of several laboratory indicators of kidney damage.

Presently, herbal medicine practitioners primarily use Crataeva to treat kidney and prostate problems. The bark of the tree is particularly used to treat infections of the urinary tract, kidney stones as well as benign prostatic hypertrophy (BPH). Researches undertaken by scientists have demonstrated that this particular herb’s actions support the cardiovascular system by properly maintaining the suppleness as well as openness of the arteries. In addition, it is believed that Crataeva has beneficial uses either as an effective diuretic or a herb that slows down or hinders the formation of stones inside the organs. Both the barks as well as the leaves of the tree are extensively utilized for preparing herbal medications. Moreover, Crataeva possesses diuretic, anti-inflammatory, demulcent (soothing or mollifying), lithontriptic (stone dissolving or destroying in the organs) and tonic (stimulant) properties. The bark of this tree generates ceryl alcohol, lupeol, friedelin, diosgenin and betulinic acid.
