Propolis contains a certain amount of lead and is not suitable for long-term use.
Propolis should not be taken for a long time.
Propolis is a gel-like solid substance synthesized by worker bees from resin collected from plant buds or tree bark wounds, mixed with secretions from their mandibular glands and beeswax. Its main components include flavonoids, terpenes, aromatic substances, and organic acids, as well as various biologically active substances such as amino acids, vitamins, and polysaccharides. It has antibacterial, anti-mold, and antiviral effects, and also functions to lower blood pressure, prevent gastric ulcers, resist radiation, and fight tumors, thus gaining favor among some consumers. However, some people take it long-term, believing it can cure illness when sick and prevent illness when well, but this is actually a mistaken practice.
Propolis is a potent natural antibiotic. If a healthy person takes propolis long-term, it is no different from taking antibiotics for a long period, and will inevitably cause harm to the body. Moreover, propolis has a complex composition and contains a certain amount of the heavy metal lead. Long-term use can lead to cumulative poisoning from lead, damaging the nervous system and causing peripheral neuritis, resulting in motor and sensory disorders. Therefore, healthy people should not take propolis long-term.
