Therapeutic Indications

Haridrā is described by Ācārya Charaka as one of the finest Raktashodhaka dravyas and a key Kuṣṭhaghna (anti-skin disease) herb.
It detoxifies Āma (metabolic toxins), purifies the blood, supports liver function, and enhances the complexion.

It is beneficial in:

• Raktadushti (Impure blood, inflammation)

• Kuṣṭha (Skin diseases, acne, eczema, psoriasis)

• Prameha (Diabetes, metabolic disorders)

• Śotha (Swelling, inflammation, arthritis)

• Vrana (Ulcers, wounds, skin infections)

• Jvara (Fever of Pitta or Kapha origin)

• Anāha (Indigestion, bloating)

• Arśas (Piles, bleeding hemorrhoids)

• Visharoga (Poisoning, toxicity)

• Yakṛt vikāra (Liver disorders, jaundice)

Externally, Haridrā is used in lepas (pastes) for skin eruptions, wounds, and inflammation.
