ABSTRACT
Pickering emulsion, a kind of emulsion stabilized only by solid particles, has become a new research hotspot of chemistry, material science and medicine industry, because it can be used to prepare the emulsions with superior stability, low toxicity and biocompatibility, which are useful to improve the stability and bioavailability of Chinese materia medica (CMM) volatile oils. This review presented recent systematic studies, characteristics of Pickering emulsion and its applications in CMM volatile oils in recent years, in order to provide basis for the application of Pickering emulsification technology in CMM volatile oils.
ABSTRACT
Volatile oil is the representative effective component of aromatic Chinese materia medica (CMM), which has pharmacological activities such as anti-anxiety, antidepressant, sedative and neuroprotective effects. They can regulate people’s mood through olfactory, skin and other ways of administration, play a role in regulating consciousness, and have unique advantages in the prevention and treatment of emotional diseases such as depression, anxiety, insomnia and so on. As a unique health service resource, it can also play an auxiliary role in the prevention, treatment and rehabilitation of other physical and mental diseases. However, at present, there are some problems, such as weak basic research, lack of effective and high-quality preparations and products. In this paper, the relevant research literature is summarized, the administration route, efficacy and action mechanism are systematically combed, the existing problems are analyzed and the countermeasures are put forward, so as to provide reference for its in-depth research, further development and utilization.
