Can patients with a cold drink Ophiopogon japonicus (Mai Dong)?

Generally, individuals with a common cold may consume Ophiopogon (McDoor) in moderation when experiencing symptoms of Yin deficiency with dry cough or sore throat. However, it is not recommended for cases of wind-cold感冒 or脾胃虚寒 (spleen-stomach cold deficiency). If uncertain, it is advisable to consult a healthcare professional beforehand. Detailed explanations are as follows:

Ophiopogon has functions of nourishing Yin, moistening the lungs, promoting body fluid production, and relieving thirst. It is suitable for symptoms such as dry throat pain and dry cough with minimal phlegm caused by Yin deficiency. If the common cold is accompanied by these symptoms, moderate consumption of Ophiopogon tea may help alleviate discomfort, especially symptoms triggered by dry environments or insufficient body fluids.

However, Ophiopogon has a cold nature. If the感冒 is of the wind-cold type, characterized by severe chills, mild fever, and clear nasal discharge, it is not advisable to consume it. Its cold nature may exacerbate internal coldness, prolonging the illness. Additionally, if the patient suffers from a weak spleen and stomach or is prone to diarrhea, taking Ophiopogon might further impair spleen and stomach functions, affecting digestion and recovery.

During a cold, it is advisable to eat light, easily digestible foods and avoid spicy or irritating foods that could worsen symptoms. Ensuring sufficient sleep can aid in the recovery and regulation of the immune system.
