The use of water for therapeutic purposes is mentioned in the Old Testament, where it is stated that Naaman, who suffered from skin disease, dipped himself seven times in the Jordan and was cured. The New Testament records a case of congenital blindness cured by washing in the River Siloa. Balneotherapy and Hydrotherapy were not unknown in Talmudic times. The Talmud mentions a special season between Easter and Whitsun during which people used to go to the spas to take the waters or mudbaths. The cure lasted twenty-one days. In the Temple a special doctor was appointed to attend the priests for intestinal trouble caused by their excessive eating of the flesh of sacrifices and the treatment prescribed for them was the drinking of the water of Siloa.[23]

In Bombay the Manmala tank at Matunga, the major portion of which has been recently filled up and on which the Sassoon Reformatory now stands, has a reputation for curing measles. People from distant parts bring their children to this tank and the nymphs residing in it seldom fail to cure them of the malady. We are not aware of any other city well or tank gifted with such healing powers, but there are several in the Bombay Presidency. The Folklore notes of Gujarat mention a few. The water of the Krukalas well in the island of Shankhodwar is believed to cure fever and diseases caused by morbid heat. A draught of the water of the Gomukhi-Ganga, near Girnar, gives one absolute immunity from an attack of cholera. The water of a gozara well (i.e., a well which is polluted owing to a person drowned in it) cures children of bronchitis and cough. There is a well near Ramdorana, of which the water is effective against cough, and the water of the Bahamania well near Vasawad is credited with the same virtue. The water of the Mrigi Kund near Junagadh cures leprosy. The Pipli well near Talawad is well-known for the stimulating effect of its water on the digestive organs. The residents of Bombay, however, need not go to Talawad for this boon. There are in the city the Bhikha Behram well on Churchgate Street and the High Court well on Mayo Road renowned for similar properties of their water. In Northern India hydrophobia is believed to be cured if the patient looks down seven wells in succession, while in Gujarat when a person is bitten by a rabid dog, he goes to a well inhabited by a Vâchharo, the spirit who curses hydrophobia, with two earthen cups filled with milk with a pice in each, and empties the contents into the water. In the island of Shiel there is a vav called Than-vav where mothers who cannot suckle their children for want of milk wash their bodices which, when subsequently put on, are believed to cause the necessary secretion of milk.

It was recently brought to my notice that the guardian spirit of a well in Lonavla also possessed the gift of blessing mothers with milk. After that well had been dug, a goat was offered by the owner of the well to the spirit. This offering proved most unacceptable and the waters of the well at once dried up. The owner implored pardon and vowed that no animal sacrifice would ever again be offered, and that milk and ghee would be presented instead. This had the desired effect and the guardian spirit of the water has since been most friendly. “A few months ago,” said my informant, “a young lady was desirous of getting milk for her new-born babe. After fruitless attempts for a fortnight, she took an oath that she would present to the water-saint ghadas of milk and ghee and she was forthwith blest with milk for the infant.”

In the Konkan the water of a well drawn without touching the earth or without being placed upon the ground is given as medicine for indigestion.

There are ponds at Manora in the Goa State and Vetore in the Savantwadi State, the water of which is used for the cure of persons suffering from the poison of snakes, mice, spiders and scorpions.

If a person is bitten by a snake or other poisonous reptile, no medicine is administered to him, but holy water brought from the temple of the village goddess is given to him to drink and it is said that the patient is cured.

At Shivam in the Ratnagiri district people use the tirtha of a deity, or the water in which its idol is washed, as medicine for diseases due to poison. It is the sole remedy they resort to in such cases.

The water of seven tanks, or at least of one pond, in which lotuses grow, is said to check the virulence of measles and smallpox.

A bath in a tank in the Mahim district is said to cure persons suffering from skin diseases.

The well at Sihor in Rajputana is sacred to Gautama and is considered efficacious in the cure of various disorders.
