What is the shelf life of propolis?

Propolis has strong antiseptic and antioxidant properties and can be stored for a long time in a sealed, dark place, but the shelf life indicated on the manufacturer's trademark is generally three years. If stored in the refrigerator it can last longer.

What is Propolis

Propolis is an extremely rare natural resource, known as "purple gold", and contains more than 300 nutrients in 20 categories. Among the ingredients of propolis, the most representative active substances are quercetin among flavonoids, terpenes and caffeic acid phenethyl ester among organic acids. Quercetin is an active ingredient in many Chinese medicinal materials and has a wide range of physiological and pharmacological effects. Quercetin, also known as rutin or rutin, has vitamin P-like effects. Data show that quercetin has the effects of dilating coronary blood vessels, lowering blood lipids, and anti-platelet aggregation, and has a synergistic effect with aspirin. It can inhibit the release of endothelin by endothelial cells in different states to reduce the tension of blood vessels and provide a basis for preventing thromboembolism. For many years, it has been mainly used clinically as a capillary hemostatic drug and an auxiliary antihypertensive drug. In addition to flavonoids, propolis also contains aromatic volatile oils, terpene compounds, organic acids, flavanols, alcohols, phenols, aldehydes, ketones, esters, ether compounds, enzymes and inorganic salts. Propolis is like a natural "medicine storehouse".

How to choose a really good propolis capsule

First look at the national approval document. When choosing propolis, the first thing to look at is the national approval document. These functions are approved only after necessary clinical trials and expert reviews by authoritative organizations designated by the Ministry of Health, which is quite strict.

Second, look at the time of listing. The longer the time, the better the effect. Fake propolis and inferior propolis will disappear in 1 to 2 years at most. Only products with good effects and quality can last for many years. Therefore, you must choose a brand that has a fixed sales location and a long history.

Third, look at word of mouth. As the saying goes, "birds of a feather flock together", diabetics must go to a propolis specialty store to see for themselves and consult fellow diabetics who are taking propolis to find out whether propolis is good or not. If a store selling propolis is often visited by diabetics, then it can be right.

Fourth, look at the strength. Small workshops cannot produce any good products, so when choosing propolis you must consider the strength of the company. For example, whether it has passed the national GMP production standards, whether there are sufficient propolis raw materials, whether the storage environment of propolis meets the standards, whether the lead and mercury purification technology is up to standard, etc., all of these can be learned through newspapers, certificates and other channels.
