Can boiling three-lobed yam and using the water to wipe the body help reduce fever?
Generally, using boiled water from *Tinospora sagittata* (San Ye Qing) to wipe the body can help reduce body temperature. The detailed explanation is as follows:

*Tinospora sagittata* has a cool nature. When boiled, its active components dissolve into the water. When applied to the skin, the cooling components may be absorbed through the skin to help soothe heat and restlessness. At the same time, evaporation of the water helps remove surface body heat, achieving physical cooling. This method is particularly suitable for mild fever to assist in relieving discomfort. It is gentle and non-irritating, placing no additional burden on the body, and is one of the commonly used traditional Chinese methods for auxiliary cooling.
Select high-quality fresh or dried *Tinospora sagittata*. Wash thoroughly with clean water before boiling, then bring to a boil and allow to cool to a suitable temperature before use, avoiding excessive cold that may irritate the skin. When wiping, focus on areas rich in blood vessels such as the forehead, armpits, and groin to promote rapid heat dissipation. After wiping, dry the skin promptly with a clean towel and take care to stay warm and avoid catching a chill. Store *Tinospora sagittata* properly—keep fresh material in a cool place and store dried material in a sealed container to prevent moisture. If fever persists or symptoms worsen, seek medical attention promptly and do not rely solely on this method.
