The Efficacy and Function of Scrophularia ningpoensis (Fat Sea)
Recently, I've been coughing incessantly due to excessive internal heat (a traditional Chinese medicine concept referring to bodily imbalance), feeling quite unwell. I heard that Sterculia lychnophora (Pang Dahai) might help alleviate the symptoms. I'd like to ask the doctor, what are the effects and benefits of Sterculia lychnophora?

Pangdahai (Sterculia lychnophora), is a common traditional Chinese medicine, mainly derived from the mature seeds of the Sterculia plant in the Malvaceae family. It has a sweet taste and cold nature, and is associated with the lung and large intestine meridians. It has functions of clearing heat, moistening the lungs, relieving sore throat, detoxifying, and promoting bowel movements. Its therapeutic effects and benefits are mainly reflected in the following:
1. Pangdahai contains acetylcholine, which can stimulate intestinal motility and promote defecation, showing good efficacy for constipation and difficult bowel movements caused by excessive heat accumulation in the large intestine.
2. Pangdahai has effects of clearing heat, detoxifying, moistening the lungs, and relieving cough. It is significantly effective for symptoms such as hoarseness due to lung heat, dry cough without phlegm, and dry, sore throat. It helps relieve throat discomfort by soothing the throat and moistening the larynx, making it an effective medicine for treating throat disorders.
3. Alleviating edema: The diuretic components in Pangdahai help promote the elimination of excess fluid from the body, thereby reducing edema.
4. Prevention of hypertension: Components such as pangdahai素 and Astragalus gum can stimulate smooth muscle contraction and may help prevent hypertension.
Caution should be exercised in individuals with spleen-stomach deficiency cold and diarrhea. Long-term or excessive use should be avoided to prevent diarrhea or other discomforts.
