Raphanus Seed

Raphanus Seed

　　【Raphanus Seed】These are the dried seeds of the annual herbaceous plant raphanus (commonly known as radish), which are oval-shaped and rich in oil. They have a pungent, sweet, and neutral taste, and are non-toxic. They function to regulate qi, calm wheezing, aid digestion, and resolve phlegm. The *Compendium of Materia Medica* states: “The efficacy of raphanus seed lies primarily in regulating qi. In its raw form, it promotes upward movement; when cooked, it facilitates downward movement.

　　When it moves upward, it helps expel wind-phlegm, disperse wind-cold, and bring out rashes and sores; when it moves downward, it calms wheezing and coughs caused by phlegm, regulates post-diarrheal tenesmus, relieves internal pain—all of which are effects of regulating qi.” Li Shizhen personally consumed raphanus seed and noted its effect on regulating qi, stating that it “truly delivered remarkable results.”

　　Raphanus seed is a commonly used traditional Chinese medicinal herb and is produced in various regions.
