It is recorded in Shennong's Classic of Materia Medica that yam is the top grade of Chinese medicine, which can "tonify the middle energizer, invigorate qi, promote muscle growth, make people's ears bright and eyes bright after long-term service, and prolong their life". It can be seen that the ancient people also recognized the health-keeping effect of yam.
In modern Chinese medicine, yam is considered to be sweet in taste and gentle in drug effect, which mainly has the effect of "benefiting qi and nourishing yin" and has a good effect on strengthening spleen, benefiting lung and consolidating kidney.

Yam is sweet and can benefit the spleen, which has a good effect on qi deficiency and yin deficiency of the spleen and stomach. For people with insufficient spleen and stomach, you can often eat yam in your life to supplement your spleen and stomach.
For example, when we have diarrhea, loose stool, poor appetite, abdominal distension, and burnout due to deficiency of spleen and stomach, we can directly crush yam into yam powder and mix it with warm boiled water for drinking.
If you don't want to bother, you can also drink porridge with yam directly. Sticking to eating can also have the effect of invigorating the spleen and stomach.
2. The effect of yam on benefiting lung
Yam has a good tonic effect on lung qi and lung yin, so it is also very helpful for people with weak lung function to eat yam regularly.
For example, people with lung qi deficiency and lung yin deficiency often have cough, phlegm, fatigue, asthma, general fatigue, etc. At this time, insisting on eating yam can obviously improve lung function.
3. The effect of yam on strengthening kidney.
Yam has a certain tonic effect on kidney yin and kidney yang, and it also has a good astringent effect, so if you eat yam regularly, it can also play a certain role in consolidating kidney.
For example, the well-known "Liuwei Dihuang" uses yam, which can help people to nourish yin and strengthen the kidney; For people with weak kidney yang, Chinese medicine often uses yam in combination with Lindera root, Radix Rehmanniae Preparata, Radix Morindae Officinalis, Herba Epimedii, Eucommiae Cortex, etc., and its function of consolidating kidney and supporting yang is also very good.
Of course, although yam has a good tonic effect, there are still some people who are not suitable for eating too much yam. For example, the following groups of people are not suitable for eating more yam in their lives.
1, people with heavy body moisture are not suitable to eat more yam.
Although yam has a good tonic effect, its taste is sweet and moist, and excessive consumption can easily cause stagnation of dampness and evil in the spleen and stomach. In particular, people with heavy dampness in their bodies should not eat more yam. If you want to eat it, try to use it with Chinese herbal medicines that can help digestion and remove dampness.
2. People with excess heat in their bodies are not suitable to eat more yam.
Although the tonic effect of yam is good, if it is eaten too much, there may be side effects of helping yang to make a fire. Therefore, for people who are not deficient in their own physique and have real heat and evil, try to eat less yam.

Although yam is also a kind of food, it is found that a small number of people in life are allergic to yam. For example, this kind of people will have skin allergies, redness, itching and pain after touching or eating yam. Of course, it is not suitable for this kind of people to eat more yam.
