Introduction

Under normal circumstances, the nature of lotus seeds is neither cooling nor heating, but rather neutral in properties. Although lotus seeds themselves are mild, the lotus seed embryo (li xin) has a bitter and cold nature and flavor. Excessive consumption may irritate the gastrointestinal tract; individuals with spleen-stomach deficiency cold or those prone to diarrhea should remove the lotus seed embryo before consumption. Additionally, lotus seeds contain a relatively high amount of starch, and excessive intake may cause abdominal distension. It is recommended to limit consumption to 15–30 grams per serving.

In general, lotus seeds are neither cooling nor heating in nature, but are considered neutral foods. The detailed analysis is as follows:

Lotus seeds have a sweet and astringent taste and enter the heart, spleen, and kidney meridians, possessing functions such as strengthening the spleen and stopping diarrhea, benefiting the kidneys and astringing essence, and nourishing the heart and calming the mind. However, if the lotus seed embryo (lotus heart) is separated and used alone, it has a bitter and cold nature, prominently exhibiting effects of clearing heat, reducing fire, lowering blood pressure, and strengthening the heart, which differs from the overall neutral nature of the lotus seed.

Although lotus seeds are generally mild in nature, the lotus heart is bitter and cold, and excessive consumption may irritate the gastrointestinal tract. Individuals with a cold spleen and stomach constitution or those prone to diarrhea should preferably remove the lotus heart before consumption. Additionally, lotus seeds contain considerable starch, and excessive intake may lead to bloating. It is recommended to limit each serving to 15–30 grams. Furthermore, as lotus seeds can be used both as food and medicine, individuals with special constitutions or health conditions should consult a qualified physician or nutritionist before consumption to ensure safety.
