Rubia cordifolia is a perennial prickly creeper or climber with a wide range of morphological characters. The roots contain a mixture of purpurin (trihydroxy anthraquinone) and munjistin (xanthopurpurin-2-carboxylic acid), and small amounts of xanthopurpurin or purpuroxanthin and pseudopurpurin (purpurin-3-carboxylic acid). Several substituted naphthoquinones and hydroxy anhraquinones and their glycosides have been isolated from the roots. Aldehyde aceate, dihydromollugin and rubimallin showed antibacterial activities.

Indications:
The roots are credited with tonic, astringent, antidysenteric, antiseptic, mild diuretic and detoxification properties. They are used in rheumatism and form an ingredient of several Ayurvedic preparations. The roots are said to be active against Staphylococcus aureus and are made into a paste for application into ulcers, inflammations and skin troubles. Roots are used also for coloring medicinal oils. A decoction of leaves and stems is used as a vermifuge.

Dosage:
1 capsule twice a day after meals with water.
