Overview of the efficacy and functions of fried radish seeds

Fried radish seed is a processed product of the traditional Chinese medicine radish seed, which has the effects of eliminating food and swelling, lowering qi and reducing phlegm. Its main functions are reflected in the digestive system and respiratory system: it can not only treat abdominal distension and fullness caused by food accumulation and qi stagnation, but also relieve cough and asthma symptoms caused by phlegm and qi stagnation. Modern research shows that its active ingredients such as sinapine and radishin can promote gastrointestinal motility, antibacterial and anti-inflammatory effects. In clinical application, attention should be paid to the difference from raw radish seeds. After frying, the medicinal properties are milder and more suitable for people with weak spleen and stomach.

Detailed explanation of digestive system regulation

Li Shizhen of the Ming Dynasty recorded in "Compendium of Materia Medica": "Rapid seeds can cure phlegm and have the effect of pushing down walls." Roasted radish seeds improve digestive function through the following mechanisms: 1) stimulating the gastric mucosa to reflexively increase the secretion of digestive enzymes; 2) enhancing small intestinal propulsive movement; 3) regulating the balance of intestinal flora. Clinical observation shows that it has a particularly good effect on meat stasis, and is often used in combination with hawthorn and Shenqu. It should be noted that overdose may cause mild diarrhea. It is recommended that the daily dosage be controlled at 6-10 grams.

Respiratory system application characteristics

In the "Sanzi Yangqin Decoction" created by Zhang Xichun, a famous doctor in the Qing Dynasty, fried radish seeds are combined with white mustard seeds and perilla seeds, which has become a classic combination for resolving phlegm and relieving asthma. Its mechanism of action includes: 1) diluting respiratory secretions; 2) inhibiting airway inflammatory response; 3) regulating immunoglobulin levels. It is especially suitable for chronic bronchitis in the elderly, cough due to food accumulation in children and other diseases. Studies have shown that its expectorant effect is better than that of ammonium chloride, and it has no central inhibitory effect.

Modern research and usage notes

Modern pharmacology has confirmed that the glucosinolates contained in fried radish seeds produce active substances after enzymatic hydrolysis. Special attention should be paid when using it: 1) People with Qi deficiency should use it with caution; 2) It is not suitable to take it with ginseng (the "New Materia Medica" records that they are mutually exclusive); 3) Fry until it is slightly swollen and fragrant. If it is overcooked, it will be ineffective. Storage needs to be moisture-proof and moth-proof, and it is recommended to store it in a cool and dry place.

Summary and reasonable application suggestions

As a traditional Chinese medicine with the same source of medicine and food, fried radish seeds can be used for long-term conditioning at a safe dosage. Recommendations: 1) For mild food indigestion, 3 grams can be used instead of tea; 2) For those with excessive phlegm, cough and asthma, it should be combined with pinellia ternata and tangerine peel; 3) The dosage for children should be halved. Pay attention to the difference between raw products and fried products. The strong nature of raw products is to stimulate vomiting, while the slow nature of fried products is to reduce gas. If an allergic reaction occurs, use should be discontinued immediately.
