Drugs used for fomentation include Varuṇa, Guḍūci, Śigru, Mālatī, Bṛhat Pañcamūla etc or animal-based articles (flesh and heads of animals and birds) are mixed up with sour, salt or unctuous substances and urine, milk, etc. and decocted in a pitcher in such a way that the vapour does not leak out. Then, a pipe made up of leaves of Vaṃśa, Karañja or Arka with its fore part having the shape of the trunk of an elephant is inserted into the pitcher. The pipe required should be of one vyāma (91.44cm) or half a Vyāma (45.72 cm) length, with its circumference being one-fourth of a Vyāma (22.86 cm) in its proximal end, one-eighth of a Vyāma in the distal end, and curved twice or thrice. All the clefts in the pipe should be well covered with leaves that alleviate Vāta. The well-massaged patient should then get this steam through the curved pipe. Curvatures of the pipe help in lessening the intensity of steam and thus help in providing a comfortable fomentation experience. This fomentation technique is called Nāḍi Sveda

Indications: – Vātapradhāna conditions, Sandhigata Vāta
