Test your ability to identify an herb sample from iTCM's database of 212 full-color herb photos.
- Customize your testing session to include only the categories or individual herbs you need to work on. Or select all the categories and choose the randomize option to comprehensively review everything you've ever learned in herbs class.
- Type your answer in pinyin or choose from a list of Latin translations.
- At any time you can get extra help by asking to see the herb's category and/or properties.
