What are the effects of purple yam

Purple yam is a more common type of yam. Its nutritional value is better than that of ordinary yam. Eating some of it regularly can nourish blood. It is also very effective in preventing aging and kidney deficiency. It can strengthen muscles and bones and beautify the skin. Eating some of it regularly can promote digestion, moisten the lungs and relieve cough, and nourish the kidneys.

1. Replenish Qi and nourish blood

Blood deficiency should be treated by nourishing blood. Foods that are good at replenishing blood include pork liver, tendon, cuttlefish, longan meat, black soybeans, black sesame, etc. Chinese medicines that are strong at replenishing blood include donkey-hide gelatin, Rehmannia root, Angelica sinensis, Polygonum multiflorum, white peony, Millettia reticulata, mulberry, etc. Yam replenishes qi, strengthens the spleen, and nourishes the stomach. When used in combination with blood-enriching foods and medicines, it can enhance the blood-enriching effect.

2. Tonify deficiency and resist aging

Yam tastes sweet and is cool in nature. It enters the lung, spleen, and kidney meridians. "Depei Materia Medica" says that it has the function of tonifying deficiency and replenishing loss. Chen Xiuyuan, a doctor in the Qing Dynasty, once explained the function of yam, saying that it has a flat qi and enters the lungs, and its sweet taste enters the spleen. The spleen controls blood and governs the limbs. If the spleen blood is sufficient, the person will not feel hungry and the limbs will be light and agile. The lungs control qi, and if the lung qi is full, the body will be light and the qi will be doubled. Because of its thick and sticky texture, it can nourish the kidney and replenish essence. Sufficient essence will strengthen the yin and prolong life. Modern pharmacological research suggests that yam contains saponins, glycoproteins, tannins, arrestins, yam alkaloids, cholealine, starch, calcium, phosphorus, iron, etc., which have the function of inducing interferon and have a certain anti-aging material basis. From this we can see that yam can indeed replenish deficiency, heal damage, and prolong life.

3. Strengthen and nourish the skin

Yam contains mucus protein, a mixture of various glycoproteins that can provide the human body with a large amount of it. It can increase the lubrication of the mucous membrane and skin and reduce subcutaneous fat accumulation. It is a very good beauty food and can be taken alone or in a compound prescription. Yam porridge, yam wine, Liuwei Dihuang drink, Zishen Shenggan drink, etc. all have the effect of strengthening muscles and bones and nourishing the skin and fitness.

4. Nourishing Yin and Replenishing Yang

Yam can nourish yin and clear away heat. Huang Guanxiu said in "Bencao Qiuzhen" that yam is originally a food. The ancients used it in decoctions, saying that it can nourish the spleen, replenish qi and eliminate heat. Its white color enters the lungs, its sweet taste enters the spleen, and although its Qi is warm, it is mild. It replenishes the yin of the spleen and lungs, so it can moisturize the skin and hair and grow muscles.

5. Strengthen the body and eliminate evil

Yam has a mild nature and flavor, and can moisten the lungs, strengthen the spleen, and benefit the kidneys. It can both replenish yang to strengthen the functions of the internal organs and replenish yin to nourish the material foundation. What's more gratifying is that it strengthens the body without clinging to evil, so it can be used when pathogenic factors exist.

6. Strengthen the spleen and stomach, aid digestion

Yam contains substances such as amylase and polyphenol oxidase, which are beneficial to the digestion and absorption function of the spleen and stomach. It is a medicinal and food product that can nourish the spleen and stomach. It can be eaten regardless of spleen yang deficiency or stomach yin deficiency. Clinically, it is often used together with Weichangyin to treat symptoms such as spleen and stomach weakness, poor appetite, fatigue, and diarrhea.
