Abstract: As a new carrier of intercellular information, the exosomes is widely regarded as a natural drug carrier for its extensive distribution, non-immunity and targeting in human body. Chinese herbal drugs act at multiple targets and through different pathways in the prevention and treatment of diseases, but the preparation is relatively simple, there is a low solubility in the effective ingredients and low bioavailability, which limit the efficacy of the medicine. Using the new drug delivery approach of the exosomes, it is better to deliver the effective components to target cells. In this review, we reviewed the biological characteristics of exosomes and its application as a carrier of Chinese herbal drugs.
