Microorganisms inhabiting medicinal plants belong to either saprophytic or pathogenic flora. Even those microorganisms which are characterized by low pathogenicity, under favorable conditions may infect people who have had contact with them. Compound tea bags contain increased levels of bacteria in view of pharmacopoeic norms. Single plant tea bags contain less bacteria and granulated teas have the lowest content. On the other hand, the latter reveal higher level of fungal contamination. Processing of herbs, including brewing decreases the amount of microorganisms in herbal products.
栖息于药用植物上的微生物属于腐生菌或病原菌。即使是那些致病性较低的微生物，在有利条件下也可能感染与之接触的人。根据药典标准，复合茶包中的细菌含量较高。单一植物茶包中的细菌较少，而散茶的细菌含量最低。另一方面，散茶的真菌污染水平较高。草药的加工，包括冲泡，会减少草药产品中的微生物数量。
