Frequently asked questions

What does the name 'polygala' (yuanzhi/wonji) mean?

The Korean and Chinese name literally means 'far-reaching will' — the Donguibogam credits it with strengthening resolve and clarity of mind, which classical scholars linked to the ambition needed for long-term goals.

Is the leaf used differently from the root?

Yes. The Donguibogam records the leaf separately, under the name 'small grass,' noting it chiefly boosts essence and stops involuntary seminal loss from deficiency — a distinct, narrower use from the root's mind-calming role.
