Traditional Uses
Urinary and Menstrual Uses
Because of its traditionally described diuretic and emmenagogue properties, the root is used to promote the flow of urine and menstruation. Excessive use, however, has traditionally been associated with a risk of hematuria (blood in the urine).
Liver, Spleen, and Digestive Obstructions
As a cleansing and deobstruent herb, it is traditionally used with Sakanjabeen (oxymel) for flatulence believed to be associated with internal obstructions. It is also traditionally used to help resolve obstructions of the liver and spleen.
The herb may be used both externally, in the form of a poultice, and internally, as a syrup or decoction, particularly in traditional preparations for cold-natured ailments.
Skin Conditions
As a detergent or cleansing agent, the root is finely ground with vinegar and applied externally as a paste. Traditionally, this preparation has been used for various skin conditions, including:
- Bahaq—pityriasis
- Baras—vitiligo
- Jhaayin—melasma or pigmentation spots

Traditionally, Rubia cordifolia is regarded as a blood purifier. Its decoction has historically been used for conditions associated with itching, syphilis, and wounds.
