What is Rasaut?
Some of Ayurveda's most useful medicines are not raw herbs but careful preparations. Rasaut (also Rasot, or Rasanjana in Sanskrit) is one of them: a dark, concentrated paste made by boiling the bark of Daruharidra, Tree Turmeric, in water again and again until it thickens.
Its source is Indian Berberis, Berberis aristata, and its yellow colour comes from berberine. The Bhavaprakash Nighantu, a classical Ayurvedic materia medica, calls it an important traditional preparation, and Sahasra Yoga describes it as a concentrated eye-salve extract made from Daruharidra stem.
Its prime use is for the eyes, applied as a medicated eye salve (Anjana). It is also used for the skin and as an anti-infective.
Benefits of Rasaut
Eye Health
Treating eye diseases (Netra Roga hara) is listed as Rasaut's prime use. It is applied topically as an Anjana, the classical name for a medicated eye salve, and Sahasra Yoga's other name for it, Rasanjana, reflects that role.
Skin Disorders
Rasaut is classed as Kushtha hara, a remedy for skin disorders (Kushtha), and as a blood purifier (Raktashodhaka), which in Ayurveda links clear blood to clear skin.
Anti-infective Use
It is used topically as an anti-infective. Its intensely bitter taste (Tikta), light (Laghu) and dry (Ruksha) qualities and concentrated berberine content are the properties on record behind this cleansing action.
