Moderately take some tonic drugs, can strengthen the body, so as to reduce the possibility of being attacked by external evil, to achieve certain health effects.
The tonic drugs are generally divided into four categories, qi tonic drugs, blood tonic drugs, yang tonic drugs, yin tonic drugs. The most common qi tonic drugs are Codonopsis pilosulae, Astragalus membranaceus, Atractylodes macrocephala, Chinese yam, etc. The most common blood tonic drugs are Radix Rehmanniae Praeparata, Radix Angelicae Sinensis, Rhizoma Polygoni Multiflori, Colla Corii Asini, the most common yin tonic drugs are Cortex Eucommiae, Herba Epimediatae, Herba Epimediatae and the most common yin tonic drugs are Radix Panax Quinquefolius, Lilium Vulgare, Dendrobium, Rhizoma Polygonatum.
