A Chinese spa offers a super-relaxing foot massage that uses crushed herbs to heal joint pains.

Footage shows the masseuse at the Yin Yang The Original Massage and Spa clinic rubbing the feet and legs of a customer in Bangkok, Thailand.

She pressed between the fingers and added pressure to the sole before adding cream.

From a basket, the masseuse took a handful of crushed herbs wrapped on the knees with a cellophane and covered with cloth.

She proceeded to spray alcohol on the towel and lit it with a lighter, which ignited flames on top.

The heat was believed to alleviate pain in the target area, such as muscles and joints, and encourage natural healing.

After the heat was gone, the herb was removed, and the masseuse proceeded to tap the customer's legs and push and pull the feet.

Foot massage is an important component of traditional Chinese medicine. It is based on the concept of meridians or energy pathways running throughout the body, including the feet. Massaging specific points on the feet stimulates these meridians and promotes healing.
