I first wrote a negative review about limited features compared to TCM ClinicAid. But this app has a couple features that are worth having, despite herbs being listed by common name instead of pinyin or botanical name. (You can still find an herb by searching the name you know.)
Two features stand out in this app: 1) The photos and color plates are good quality. 2) There are good visual indicators of the relative intensity of properties such as flavor, temperature, channels entered, and direction of movement. For example, an herb might strongly affect the Bladder channel and only weakly affect the Lungs or Liver. An herb may move strongly downward or weakly downward, or interiorize or exteriorize. An herb the other books call “sweet” may be strongly sweet or weakly sweet, and this app gives you all that in rapidly accessible visual form.
While TCM ClinicAid and EastlandHerb are my go to apps for working with Chinese herbs, this app, TCM Herbs, definitely adds something the others don’t have.
