Synopsis

Source of validity: Traditional
Rating (out of 5): 2

Lo Han Guo (Siraitia grosvenorii), also known as monk fruit, is traditionally used in Chinese medicine primarily for its cooling and moistening properties. In Traditional Chinese Medicine (TCM), Lo Han Guo is believed to relieve cough, soothe the throat, and treat conditions associated with "heat" in the lungs, which may include symptoms like sore throat, dry cough, and sometimes mild congestion. The fruit is often used in herbal teas or decoctions aimed at clearing lung heat and moisturizing dryness, which may provide subjective relief for upper respiratory tract symptoms such as sinus congestion.

However, the direct use of Lo Han Guo for treating nasal or sinus congestion is not strongly emphasized in either traditional or scientific literature. The evidence supporting its use for sinus congestion is mainly anecdotal and based on the broader context of relieving respiratory symptoms in TCM. There is a lack of robust clinical research or mechanistic studies demonstrating its efficacy specifically for congestion. Most modern research focuses on its antioxidant, anti-inflammatory, and sweetening properties, rather than decongestant effects.

In summary, while Lo Han Guo’s use for respiratory health—including mild congestion—has historical roots in TCM, the evidence is traditional and mostly indirect. There is insufficient scientific validation for its specific role in treating sinus congestion.
