Description

This erect, glabrous, branched annual produces small white, narrowly winged hermaphrodite flowers. Root systems are very well developed. It produces floral heads that are between 6-8 milimeters in diameter.

Origin / Habitat

Eclipta Alba is commonly known as a weed that grows readily throughout tropical and sub-tropical regions of the world. It grows well in semi-shaded areas such as woodlands and prefers moist soil evidenced by its flourishing in rice paddies in Japan.

Chemical Constituents

E. alba contains three major coumestans: norwedelolactone, wedelolactone, and demethylwedelolactone. Also, flavonoids, steroids, triterpenoids, polyacetylenes, andthiophene derivitives. [2][3][4]

Plant Part Used

Leaf and sometimes root. [5]

Traditional Use

In Ayurvedic medical practices Bhangra, or Bhringaraja, is used as a general tonic, a diuretic and in treatment of spleen and liver disorders such as enlarged liver and hepatitis. Generally, the whole plant is used, but often just the juice from the leaves is used to treat edema, joint pain and fever. The juice from the Bhangra leaf can also be used topically for mild burns and abrasions. Bhangra stimulates the pitta dosha while pacifying the kapha and vata doshas. Its rasa (taste) is classified as Katu and Tikta (pungent and bitter, respectively). [5] In popular Indian culture, Bhangra is used to stimulate and improve memory. 

The leaves and sometimes roots are used in combination with Ajowan seeds in liver and gallbladder derangements and have often replaced the use of general liver tonics. 

Dosage

3-6g Powder, 4-12 ml infusion. [1]

Pharmacology

Pre-clinical

E. alba is astringent, emetic, febrifuge, purgative and tonic. Actual clinical work on E. alba is limited with only a few small pilot studies published in the literature. However its traditional use has been further verified and investigated in animal studies. [3] 

Additional animal studies have shown positive results for E. alba as having hepatoprotective properties, anti-aggressive neurological effects, a positive effect on memory,   anti-inflammatory properties and analgesic properties.[6][7][8][9]  

Clinical

In one small clinical study of mildly hypertensive males aged 45 to 50, E. alba users showed a reduction in mean arterial pressure, total cholesterol, triglycerides, plasma lipid peroxides and LDL fraction. Its use also resulted in an increased urine output. [10]

Interaction with Drugs
