Can children eat Ophiopogon japonicus (Mai Dong)?
Generally speaking, if a child has a weak constitution or symptoms of yin deficiency with internal heat, Ophiopogon japonicus (McDoor) may be consumed in appropriate amounts under the guidance of a physician. However, it is unsuitable for children with a cold body constitution or those suffering from spleen and stomach weakness. If in doubt, it is advisable to consult a doctor in advance. Detailed analysis is as follows:

When children show symptoms of yin deficiency, such as dry mouth and throat, sore throat, night sweats, or prolonged coughing, appropriate consumption of Ophiopogon japonicus can nourish yin, moisten dryness, promote body fluid production, and relieve thirst. Ophiopogon japonicus is slightly cold in nature and enters the heart, lung, and stomach meridians. It can help alleviate discomfort caused by deficiency of body fluids, especially suitable for recovery after febrile illness or for individuals with generally weak constitutions.
If a child's constitution tends toward coldness or has weak spleen and stomach function, consumption of Ophiopogon japonicus is not advisable. Its cold nature may exacerbate internal coldness, leading to problems such as diarrhea, abdominal pain, or poor appetite. Additionally, long-term excessive consumption of Ophiopogon japonicus may impair the spleen and stomach's ability to transform and transport nutrients, negatively affecting health.
Therefore, when the body constitution is uncertain, Ophiopogon japonicus should not be used casually as a regular dietary supplement. Pediatric medication must strictly follow medical advice to control dosage and avoid long-term use. Cold, raw, or greasy foods should be avoided during consumption. If adverse reactions such as reduced appetite or loose stools occur, usage should be stopped immediately.
