Effects of an Ethanol Extract of Brazilian Green Propolis
Supplement–drug interaction on CYP enzyme activity is occasionally found to cause clinically adverse events, and no report on interactions of propolis is available either in vitro or clinical. In this study, we tried to estimate the risk of an interaction between an ethanol extract of Brazilian green propolis (EEP-B55) and drugs in vitro and in vivo.

Natural rubber
Natural rubber is often vulcanized - a process by which the rubber is heated and sulfur, peroxide or bisphenol are added to improve resistance and elasticity and to prevent it from perishing. Carbon black is often used as an additive to rubber to improve its strength, especially in vehicle tires, which account for about 70% (~9 million tons) of carbon black production.
