Plant Material Introduction
The raw material of this product comes from the dried rhizomes of Polygonatum sibiricum Redoute, P. kingianum Coll. et Hemsl., or P. cyrtonema Hua, plants of the Liliaceae family. It is mainly produced in Hunan, Hubei, Guizhou, Sichuan, Anhui, and other regions in China. The 2020 edition of the Chinese Pharmacopoeia records Polygonatum. Polygonatum is a traditional Chinese medicine that tonifies qi and nourishes yin, strengthens the spleen, moistens the lungs, and benefits the kidneys, and is known as ‘immortal’s leftover grain.’ Its main active components, Polygonatum polysaccharides and saponins, exhibit extensive biological activities.
Core Efficacy
Polygonatum sibiricum extract has a substantial research basis in metabolic health and immune support. Studies on Polygonatum polysaccharides suggest that they may help maintain healthy glucose metabolism and insulin sensitivity, as well as support pancreatic health.
In terms of immune regulation, Polygonatum polysaccharides can support macrophage phagocytic function and NK cell activity. Additionally, Polygonatum has traditional application value in antioxidant support, liver protection, and cardiovascular health support.
Regulatory and Regional Access Status
The information below is compiled from publicly available regulatory data. Actual market access should be based on the latest regulations in the target country.
| Region/Country | Regulatory Status | Key Notes |
| China (NHC/NMPA) | Health Food Ingredients / New Resource Foods | According to the 2020 edition of the Chinese Pharmacopoeia and standards such as GB 16740; some varieties have been included in the health food ingredient catalog or can be used in ordinary food catalogs, and the latest regulatory status of each variety needs to be specifically verified. |
| Japan (MHLW) | Food Additives / Health Food Ingredients | Used as extracts for food additives or health food ingredients; some varieties need to be reported under the functional labeling food system. |
Application Directions and Recommended Dosage
| Application Direction | Recommended Addition Amount | Applicable Dosage Form | Remarks |
| Oral solid beverages/capsules | 200~500 mg/day | Tablets, capsules, granules | Can be combined with immune-supporting nutrients such as vitamin C and zinc |
| Oral solid beverage / granule | Determined according to specifications | Strip packaging, bag packaging, can packaging | Can be combined with other functional ingredients, recommended to control with standardized extracts |
| Compressed candy / capsule | Determined according to specifications | Tablets, hard capsules | Each capsule is recommended to contain 250~500 mg of extract, taken 2~3 times daily |
| Oral liquid / functional beverage | According to specifications | Glass bottle, PET bottle | It is recommended to disperse in warm water first before adding to the system, pay attention to pH stability |
| Personal care and skincare products | 0.1~2.0%(w/w) | Lotion, serum, mask | Solubility and stability need to be evaluated according to the formulation system |
Recommended Daily Dosage Reference
- For general health maintenance, the daily intake of Polygonatum polysaccharides should not exceed 0.7g, and continuous use for more than one month is not recommended; for medicinal purposes, strictly follow your doctor’s instructions and do not increase the dose without consultation.
Other Precautions
- Contraindications based on constitution: Not to be used by individuals with spleen deficiency with excessive dampness, cough with copious phlegm, cold-induced diarrhoea, or qi stagnation with abdominal distension. The extract has a particularly heavy and greasy nature, which may rapidly exacerbate the accumulation of dampness, leading to problems such as a thick, greasy tongue coating and sticky stools.
- Risks of Concomitant Use: Diabetic patients taking this alongside hypoglycaemic medication should monitor their blood glucose levels, as the extract’s blood-sugar-regulating properties may induce hypoglycaemia; long-term use requires vigilance regarding metabolic interactions with anticoagulants and antihypertensive drugs.
- Special populations: Pregnant women, breastfeeding women, children, and those with impaired liver or kidney function or autoimmune diseases should consult a doctor to confirm safety before use.
- Warning signs: If skin itching, a rash, abdominal distension or pain, fatigue or darkening of urine occur after taking this product, discontinue use immediately and seek medical attention to rule out an allergic reaction or organ damage.
