Introduction

Generally speaking, from the perspective of Traditional Chinese Medicine (TCM), longan is warm in nature, and excessive consumption may easily lead to internal heat. TCM holds that longan is sweet in taste and warm in property, entering the heart and spleen meridians. It has the functions of tonifying the heart and spleen, nourishing blood, and calming the mind, and can be used for conditions such as deficiency of qi and blood, palpitations, forgetfulness, insomnia, sallow complexion due to blood deficiency, etc. Moderate consumption can help replenish blood; however, because of its warm nature, overconsumption should be avoided.

Generally speaking, from the perspective of Traditional Chinese Medicine (TCM), longan is considered warm in nature, and excessive consumption may easily lead to "heatiness." A detailed explanation is as follows:

According to TCM, longan is sweet in taste and warm in nature, affecting the heart and spleen meridians. It has the effects of tonifying the heart and spleen, nourishing blood, and calming the mind. It can be used for conditions such as deficiency of qi and blood, palpitations, forgetfulness, insomnia, and sallow complexion due to blood deficiency. Moderate consumption can help replenish blood; however, because of its warm nature, overeating may cause heat-related symptoms such as nosebleeds, mouth ulcers, and sore throat. Therefore, it's important to consume longan in moderation. Additionally, longan contains a relatively high amount of sugars and is a high-calorie fruit, so it is not recommended for individuals with diabetes, hyperlipidemia, hyperuricemia, obesity, or even hypertension.

It is advisable to develop healthy eating habits, eat smaller meals more frequently, practice portion control, avoid overeating, and maintain a generally light diet.
