The Efficacy and Function of Dishan (Di Sha)
Generally, Di Sha (a medicinal substance) has various functions and effects such as anti-inflammatory action, relieving cough and expelling phlegm, strengthening the spleen and eliminating food accumulation, clearing heat while moistening the lungs, and nourishing yin to tonify the kidneys. The specific details are as follows:

1. Anti-inflammatory Action
Some components of Di Sha have the effect of inhibiting inflammatory responses, which can reduce inflammation and swelling in tissues. This characteristic gives Di Sha a certain potential in treating inflammatory diseases.
2. Relieving Cough and Expelling Phlegm
Di Sha has good effects in relieving cough and removing phlegm. It helps promote smooth lung function and effectively alleviates symptoms of respiratory diseases such as excessive coughing with phlegm and unsatisfactory expectoration. When external pathogens invade the lungs or phlegm accumulates within the lungs, Di Sha can help resolve phlegm, making it thinner and easier to expel by coughing.
3. Strengthening the Spleen and Eliminating Food Accumulation
Di Sha is commonly used in treating infantile malnutrition (gan-ji) and indigestion. It helps promote digestion and absorption of food by strengthening the spleen, thereby improving symptoms of indigestion.
4. Clearing Heat and Moistening the Lungs
Di Sha can clear internal heat and moisten the lungs. When the lungs are invaded by heat pathogens, causing symptoms of lung heat such as fever, cough, and yellow, thick phlegm, Di Sha can clear the heat pathogens from the lungs and reduce inflammatory responses. For symptoms such as dry cough and minimal phlegm, Di Sha can also moisten the lungs, alleviating dryness in the throat and coughing.
5. Nourishing Yin and Tonifying the Kidneys
Di Sha also has a certain effect of nourishing yin and strengthening the kidneys. When symptoms such as soreness and weakness in the lower back and knees, dizziness, tinnitus, tidal fever, and night sweats occur, Di Sha can nourish kidney yin, replenish the body's yin fluids, and alleviate symptoms of kidney yin deficiency.
When using Di Sha, it is important to follow medical advice, avoiding excessive or long-term use to prevent adverse effects on the body. Additionally, pregnant women, nursing mothers, and patients with special medical conditions should use Di Sha cautiously under the guidance of a physician.
