（本经上品）
【气味】辛甘，微温，无毒。
【主治】主大风邪气，阴痿不起，强筋骨，安五脏，补中，增志，益气。
【核】曰∶出蜀中，今江淮、河东州郡亦有，不若蜀中者佳，多生山林内。叶似茗，经
冬不枯；又似麦门冬叶而浓大，秋深结实。根如连珠，宿根青色，嫩根紫白，以连珠多肉者
为胜。土人采根，同黑豆煮紫，殊失气味。一种山 根极相似，但色白。土人以醋煮之，杂
巴戟内，莫能识别。但击破之，紫而鲜洁者伪也，紫而青白，兼糁粉色，其理小暗者真也。
修
先人云∶草木至冬，莫不随天地气化而藏，独此不凋，与天相戟，当为冬肾之生物也。
其精志与骨，咸肾所司，欲其生发者，仗此大有所裨。
【 】曰∶深秋结实，经冬不凋，反地之阳杀阴藏，得天之阳生阴长，可判属肝。而以
戟、以辛，又可判属肺矣。诚肺肝秉制为用之用药也。故主天有八风，不从乡来者之外所因。
与经有五风，触五藏之内所因，或肝失用而阴痿不起；或形失生而筋骨不强；或志从阴藏而
颓；或气从阳杀而损，靡不因风入中虚，戟以击之。雷公法秉制之宜，阅杞菊生成，斯义自
见。
（不曰巴戟地，而曰巴戟天，虽似弄巧，实出至理。如是乃可合天有八风，经有五风，
御五位，触五藏也。）
[Shennong Bencao Jing, Upper Grade]
[Taste and Nature] Acrid, sweet, slightly warm, non-toxic.
[Indications] Mainly treats severe wind-pathogenic qi, impotence with inability to erect, strengthens sinews and bones, calms the five Zang organs, tonifies the middle Jiao, enhances willpower, and benefits Qi.
[Verification] It is stated: Bajitian grows in Shu region; currently, it is also produced in Jianghuai and Hedong prefectures, but not as good as that from Shu. It mostly grows inside mountains and forests. The leaves resemble tea leaves and do not wither through winter; they are also similar to Ophiopogonis Radix (Mendong) leaves but thicker and larger, bearing fruit deep in autumn. The root resembles a string of pearls; the perennial root is greenish, while the tender root is purplish-white. Those that are pearl-like and fleshy are superior. Local people harvest the roots and boil them with black soybeans until purple, which greatly destroys their original taste and nature. There is a type of wild root extremely similar to Bajitian, but white in color. Locals boil it with vinegar and mix it into Bajitian, making it indistinguishable. However, if broken open, those that are purple and bright/clean are fake; those that are purplish-greenish-white, mixed with pink powder, and have slightly dull texture are genuine.
My late father said: Herbs and trees, upon reaching winter, all hide according to the Qi transformation of heaven and earth. Only this herb does not wither, standing like a halberd against heaven, thus it should be considered a biological product governed by the Winter Kidney. Its essence relates to Will (Zhi) and Bone, which are both governed by the Kidney. To promote its growth and development, relying on this herb provides great assistance.
[Lei Gong] states: Bearing fruit in late autumn and not withering through winter, it goes against the Earth's Yang killing and Yin hiding, yet obtains Heaven's Yang to generate and grow Yin. Thus, it can be judged to belong to the Liver. Named as "Halberd" (Ji) and having an acrid taste, it can also be judged to belong to the Lung. Indeed, it is a medicine that utilizes the controlling and regulating functions of the Lung and Liver. Therefore, it mainly treats external causes due to Eight Winds of Heaven coming from improper directions, and internal causes due to Five Winds of Meridians touching the Five Zang organs. This may manifest as Liver dysfunction leading to impotence; or loss of bodily vitality leading to weak sinews and bones; or Will declining due to Yin organ deterioration; or Qi damaged due to Yang killing. None of these are not caused by Wind pathogen entering the interior deficiency, requiring the "Halberd" to strike and dispel it. Lei Gong's methods adhere to the appropriateness of controlling transformations. By observing the generation of Lycii Fructus (Gouqi) and Chrysanthemi Flos (Juhua), this principle becomes self-evident.
(It is called Bajitian [Bajia Heaven] rather than Bajidi [Bajia Earth]. Although this seems like a clever play on words, it actually stems from profound truth. Only in this way can it correspond to the Eight Winds of Heaven, Five Winds of Meridians, defend the Five Positions, and interact with the Five Zang organs.)
