Chives are a unique vegetable in China. Traditional Chinese medicine believes that leeks have a spicy and salty taste, a warm nature, and have the effects of warming the middle and promoting qi, tonifying deficiency and benefiting yang, dispersing blood stasis and detoxifying. Chives are pruned and rejuvenated, but they last for a long time without being depleted. Therefore, they are called "evergreen grass". They are more suitable for men to eat due to their ability to stimulate positive energy, so they are also called "yangcao" or "yangcao". Modern research has also proven that leeks are rich in nutrients such as cellulose, vitamin C, B1, B2, niacin, and carotene, which have the effects of promoting appetite, improving immunity, and killing bacteria and inflammation. At the same time, it also helps to regulate blood lipids, and moderate consumption has certain benefits for hypertension, coronary heart disease, hyperlipidemia, etc. In addition, because leeks contain a large amount of crude fiber, they can enhance gastrointestinal peristalsis and effectively prevent habitual constipation and colon cancer. Although leeks have many benefits for the human body, they are not necessarily more beneficial. Eating too much can cause heat and make it difficult to digest. Therefore, people with yin deficiency, excessive fire, and gastrointestinal weakness should not eat too much. The recommended amount is about 1 liang per person per time.
Lotus root is the plump rhizome of lotus, and it is a commonly used food that can be eaten or eaten. Traditional Chinese medicine believes that the sweet and cold roots of lotus root have the effects of eliminating stasis, clearing heat, dispelling troubles and thirst, and stopping bleeding (such as nosebleeds, urinary bleeding, bloody stools, and uterine bleeding). The "Daily Materia Medica" believes that "all blood evidence should be consumed". The blood syndrome here includes symptoms such as vomiting and coughing up blood. That is to say, lotus root is beneficial for all diseases that manifest as bleeding. Due to their special physiological functions, women are more susceptible to "blood syndrome", so eating more lotus roots is particularly beneficial for women. Due to the cold nature of the lotus root, it can easily interfere with the spleen and stomach. Therefore, it is not suitable to eat raw for those with low digestive function and loose stools. In addition, it is not advisable for postpartum women to consume raw lotus roots too early. It is generally recommended to eat them 1-2 weeks after giving birth. After the lotus root is cooked, its nature changes from cool to warm, losing its ability to dissipate stasis and clear heat, and becoming beneficial to the spleen and stomach. It has the effects of nourishing the stomach, nourishing yin, benefiting blood, and stopping diarrhea, and is suitable for all types of people to consume.
