According to Ayurveda, the ancient medical system of India, Snana is not considered an Ayurvedic Treatment. Snana or Herbal Bath belongs to the Paschath Karma therapies, the treatments after the Panchakarma or the Pradhanakarma. It is viewed as a daily activity, after an oil massage called Abhyanga.
Warm water is boiled with herbs, which are chosen depending on the physique of the person. However, the water should be cooled well before having the bath. One shouldn't administer warm water on head.Cleansing agents like green gram powder and herbal shampoos assure a complete herbal and healthy bath. Bathing immediately after taking food should also be avoided. The best time is the morning or the afternoon, just before sunset.
