Can children over one year old take Ophiopogon japonicus (Mai Dong)?
Generally, it is not recommended for children over one year old to consume Ophiopogon japonicus (Mai Dong). It is advised to use medication under the guidance of a physician. The specific reasons are as follows:

The spleen and stomach functions of children over one year old are not yet fully developed. Ophiopogon japonicus is slightly cold in nature and may irritate the child's spleen and stomach, leading to spleen-stomach deficiency-cold, causing problems such as indigestion and diarrhea. Moreover, at this stage, the child's excretory organs such as the kidneys have not fully matured, and their ability to metabolize and excrete drugs is limited. Consumption of Ophiopogon japonicus may increase the burden on the kidneys and potentially cause drug accumulation, resulting in adverse effects on the body.
In addition, children may experience allergic reactions to Ophiopogon japonicus, which may initially manifest as rashes, itching, shortness of breath, and other symptoms. Without professional medical guidance, any herbal ingredients should not be randomly administered to children over one year old, to avoid adverse reactions or interference with normal growth and development.
In daily life, parents should also pay attention to the child's diet and lifestyle habits, enhancing the child's physical condition through balanced nutrition, appropriate exercise, and other methods, thus reducing the occurrence of illnesses.
