Can Ophiopogon japonicus (Mai Dong) be steeped in water and consumed for a long period?

Generally speaking, whether Ophiopogon japonicus (Mai Dong) can be steeped in water for a long time should be determined by combining individual body constitution and actual needs, as it is not suitable for everyone. Blindly consuming it for a prolonged period may cause discomfort. Specific analysis is as follows:

Ophiopogon japonicus is slightly cold in nature and has the effects of nourishing yin, promoting body fluid production, moistening the lungs, and clearing the heart. It is suitable for people with yin deficiency and fluid insufficiency to consume short-term, such as those who frequently experience symptoms like dry mouth and throat discomfort, or dry cough with little phlegm. Appropriate consumption can help alleviate these symptoms. However, even for individuals in this category, continuous long-term consumption is not recommended. Regular breaks should be taken to avoid the accumulation of coldness in the body and disruption of the body's yin-yang balance.

For individuals with spleen and stomach deficiency-cold, prone to diarrhea, or with thick腻 tongue coating, long-term consumption of Ophiopogon japonicus tea may worsen their existing discomfort. The cold nature of Ophiopogon japonicus can further damage the yang energy of the spleen and stomach, leading to increased abdominal distension and diarrhea frequency. It may also hinder the elimination of dampness from the body and further affect digestive function.

In daily life, the consumption of Ophiopogon japonicus water should be flexibly adjusted according to one's own condition. Once symptoms are relieved, the frequency of consumption can be reduced or paused, avoiding continuous long-term consumption. Additionally, attention should be paid to observing the body's reactions to ensure no additional burden is placed on health.
