Original, read line by line 東醫寶鑑 · Tangaek — Decoctions vol. 3

1. 性寒, 味辛苦, 無毒.

   Its nature is cold, its taste pungent and bitter, and it is non-toxic.

2. 主肺癰上氣咳嗽. 定喘促, 除胸中痰飮, 療皮間邪水上溢, 面目浮腫, 利小便.

   It chiefly treats pyeong-ong (lung abscess) and cough with counterflow qi. It settles hurried panting, clears damum (phlegm-rheum) from the chest, treats sasu (pathogenic water) between the skin welling upward and swelling of the face and eyes, and promotes urination.

3. 在處有之, 苗葉似薺. 三月開花, 微黃結角, 子扁小如黍粒, 色黃.

   It is found everywhere, and its shoots and leaves resemble the shepherd's purse. It flowers in the third month, pale yellow, and forms pods; the seeds are flat and small like grains of millet, and yellow in color.

   HomiclubJe (薺) is the shepherd's purse. These are brassicas whose seeds are so fine that a single pod's worth is hard to count by hand; the Korean name durumi-naengi belongs to this group.

4. 立夏後, 採實暴乾. 《本草》

   After ipha (the start of summer) the fruit is gathered and sun-dried. 《Boncho》

5. 性急, 善逐水, 有苦甛二種. 苦則下泄, 甛則少緩. 《湯液》

   Its nature is urgent and it drives out water well; there are two kinds, bitter and sweet. The bitter kind purges downward, the sweet kind is somewhat slower. 《Tangaek》

6. 隔紙炒香, 或蒸熟用之. 此藥性急, 走泄爲功, 苦者尤甚, 甛者少緩. 《入門》

   Roast it fragrant over a sheet of paper, or steam it through before use. This drug is urgent in nature and works by driving downward; the bitter kind more so, the sweet kind somewhat slower. 《Ipmun》

   HomiclubRoasting the seeds over a sheet of paper keeps such fine grains from sticking to the pan or scorching.
