What Diseases Can Walnuts Treat?
Generally speaking, walnuts can be used to treat conditions such as kidney deficiency with weak lower back, constipation due to intestinal dryness, impaired cognitive function, bacterial infections and inflammation, as well as asthma with cold lungs. Detailed explanations are as follows:

1. Nourish the Kidneys and Strengthen the Lower Back
Walnuts are warm in nature and enter the kidney meridian. They are believed to nourish the kidneys and enhance kidney function. Consuming walnuts in moderation may help alleviate symptoms caused by kidney deficiency, such as soreness and weakness in the lower back and knees, and fatigue.
2. Lubricate the Intestines and Relieve Constipation
Walnuts are rich in oils, which have a lubricating effect on the intestines. The oily components can moisten the intestines, promote peristalsis, and facilitate the elimination of fecal matter. If symptoms of intestinal dryness and constipation occur, moderate consumption of walnuts may help alleviate these symptoms.
3. Enhance Brain Function and Intelligence
Walnuts contain abundant linoleic acid and DHA, which are essential nutrients for brain and visual development. Eating walnuts in moderation may help improve memory and enhance brain activity.
4. Antibacterial and Anti-inflammatory Effects
Walnuts are rich in trace elements such as copper, magnesium, and potassium, as well as nutrients like vitamin B6 and folic acid. These components give walnuts certain antibacterial properties. In daily life, the antibacterial properties of walnuts can be utilized to clean and disinfect home environments to prevent the spread of pathogens.
5. Warm the Lungs and Alleviate Asthma
Walnuts can warm the lungs, enhance the lung's functions of dispersion and descent, and replenish kidney energy, allowing the kidneys to better receive and retain qi, thus maintaining steady and deep respiration and relieving symptoms of asthma and coughing.
As a food, moderate consumption of walnuts is beneficial to health, but they cannot replace standard medical treatment. If used as a traditional Chinese medicine, their use should follow the guidance of a qualified TCM practitioner.
