The process of a traditional Bhutanese hot stone bath is unique. It uses Menchu (medicinal water) which is nothing but fresh river water mixed with Artemisia leaves. The water is heated using river stones that are roasted on fire till they are glowing red. The temperature of the water can be increased adding more heated stones into a wooden chamber via a chute. This chamber is connected to the main tub (also made of wood) which contains the water. The holes in the chamber allow the heat to be infused into the bath (so there is no danger of being burned the hot stones) and the stones are said to release key minerals into the water which are believed to have medicinal benefits. One can soak in the water for about an hour or two after a tiring day while sipping a hot beverage. This may also be followed a salt scrub to remove dead skin cells and an oil massage to relieve tired muscles.
Hot stone bath is a traditional healing process which has been in practice for ages in Bhutan and is a very satisfying experience in itself, especially in winter. In the past, these baths served as a source of relaxation for the families after the long, hard months of farming in winter. This bath helped in relieving them of bodily stress and was believed to cure any other ailments they might have contracted during their work. Some families would even consult their astrologer to look for an auspicious day when the bath would have the most beneficial effect.
Traditionally, hot stone baths were arranged in a very rustic setup, inside a farm shed or near a river bed where there are plenty of rocks and river water available readily and in the open air, which may also provide a wonderful view of the surrounding landscape. However, this bath is provided as a spa and wellness option in many hotels and resorts which may better suit the standards of the visitor and may also cater to luxurious tastes and preferences.
