Introduction
Under normal circumstances, lotus seed heart tea, a beverage made from lotus seed hearts, mainly functions to clear heat and reduce internal fire, calm the mind and relieve restlessness, promote urination and reduce edema, alleviate symptoms of dry mouth and throat, and assist in regulating emotions. However, it should be consumed in moderation, as excessive intake may cause gastrointestinal discomfort due to its cold nature, particularly for individuals with spleen and stomach deficiency-cold who should avoid consuming too much.

Generally, as a beverage made from the embryo of the lotus seed (Nelumbinis Plumula), lotus seed heart tea offers various benefits and functions including clearing heat and reducing fire, calming the mind, promoting diuresis and reducing edema, relieving dry mouth and throat, and assisting in emotional regulation. The specific effects are analyzed as follows:

1. Clearing Heat and Reducing Fire: Lotus seed heart has a bitter and cold nature, offering a strong effect in clearing internal heat and fire. When brewed into tea, it is suitable for symptoms such as sore throat, oral ulcers, and red, swollen, painful eyes caused by excessive internal heat. Drinking this tea helps eliminate heat toxins from the body and alleviate physical discomfort caused by excessive heat, making it suitable for individuals prone to internal heat.

2. Calming the Mind: Lotus seed heart enters the heart meridian and helps clear heart fire and calm the mind. Lotus seed heart tea is suitable for symptoms such as irritability, insomnia, vivid dreams, and palpitations caused by excessive heart fire. Drinking the tea can soothe restlessness, relieve emotional instability caused by heart fire, and help improve sleep quality.

3. Promoting Diuresis and Reducing Edema: Lotus seed heart has a certain diuretic effect. When brewed into tea, it can promote urination and is suitable for symptoms such as edema and difficult urination caused by excessive dampness or fluid retention in the body.

It is suitable for symptoms such as dry mouth and throat and sore throat caused by dry heat damaging body fluids.

5.

It can assist in soothing tense emotions and help maintain a relatively calm state.

It is also important to consume lotus seed heart tea in moderation.
