【发明】颂曰∶古方皆用有刺者，治风明目最良。神仙方亦有单服蒺藜法，云不问黑白，
但取坚实者，舂去刺用。
时珍曰∶古方补肾治风，皆用刺蒺藜。后世补肾多用沙苑蒺藜，或以熬膏和药，恐其功
亦不甚相远也。刺蒺藜炒黄去刺，磨面作饼，或蒸食，可以救荒。

【气味】味甘，性温，无毒。
【主治】补肾，治疗腰痛、遗精及虚损劳乏（李时珍）。
【发明】苏颂说：古方中多用带刺的蒺藜，治疗风邪、明目效果最好。神仙方中也有单服蒺藜的方法，说不论黑白品种，只要选取质地坚实的，捣碎去刺后使用。
李时珍说：古方中用于补肾治风的，都用刺蒺藜。后世用于补肾的多用沙苑蒺藜，或者将其熬成膏状配合药物使用，恐怕它们的功效也相差不远。刺蒺藜炒至黄色后去刺，磨成粉做成饼，或者蒸熟食用，可以用来救荒。
（出自宋代《开宝本草》）

[Scent and Flavor] Sweet, warm, non-toxic.
[Indications] Tonifies the Kidney, treats lower back pain, seminal emission, and deficiency fatigue (Shizhen).
[Analysis] Song says: Ancient prescriptions all use those with thorns, which are best for treating wind disorders and improving vision. Immortal prescriptions also have methods for taking Tribulus alone, stating that regardless of color, one should select firm specimens, pound them to remove thorns, and use them.
Shizhen says: Ancient prescriptions for tonifying the Kidney and treating wind all use Spiny Tribulus (Cacumen Tribuli). Later generations mostly used Shan Yuan Ji Li (Astragali Complanati Semen) for tonifying the Kidney, or boiled it into a paste to mix with medicines; it is feared that their efficacy is not far apart. Spiny Tribulus is stir-fried until yellow, thorns removed, ground into powder to make cakes, or steamed for food, which can be used to relieve famine.
(From Song Dynasty *Kaibao Bencao*)
[Names] Daixing Cao (Star-Bearing Grass) (*Kaibao Bencao*), Wenxing Cao (Literary Star Grass) (*Bencao Gangmu*).
Shizhen says: It grows from the residual qi of grain fields, hence named Gujing Cao (Grain Essence Grass).
Zangqi says: Its white flowers resemble stars, hence names like Daixing.
[Collection and Explanation] Song says: It grows everywhere. In spring, it grows in grain fields; leaves and stems are green, roots and flowers are white.
Flowers are harvested in February and March; they are small, round, white, and star-like. They can be fed to horses to fatten them.
Roots are slightly reddish, produced in the Qin and Long regions.
Shizhen says: This herb grows in wasteland after grain harvests, abundant north and south of the Yangtze River. It grows in clumps, leaves resembling young grain seedlings. Thin stems emerge, four to five cun high. Small white flowers appear at stem tips, dotted like scattered stars. Flowers are harvested in September and dried in shade. The claim that they are harvested in February and March is erroneous.
[Scent and Flavor] Pungent, warm, non-toxic. Zangqi says: Sweet, neutral.
Daming says: Can combine with Mercury to form granules.
[Indications] Throat obstruction (Hou Bi), toothache due to wind, various sores and scabies (*Kaibao Bencao*). Headache, blindness with corneal opacity, post-varicella corneal opacity, hemostasis (Shizhen).
[Analysis] Shizhen says: Gujing Cao is light and floating in nature, able to ascend to the Yangming channel distribution. For any eye disorder, adding it yields excellent results. Its merit in brightening eyes and reducing corneal opacity seems superior to Chrysanthemi Flos (Ju Hua).
[Attached Prescriptions] One old, nine new.
Brain and eyebrow pain: Gujing Cao 2 qian, Earthworm 3 qian, Frankincense 1 qian, ground into powder. Use half a qian each time, burn in a smoking tube, and fumigate the nose according to the side of pain (*Shengji Zonglu*).
Lateral and frontal headache: *Jiyan Fang*: Use 1 liang of Gujing Cao ground into powder, mixed with wheat flour paste, spread on paper flowers, applied to the painful area, changed when dry. *Shengji Fang*: Use Gujing Cao powder and Malachite Green 1 qian each, Niter half a qian. Snuff into the nose according to the side of pain.
Persistent epistaxis: Gujing Cao ground into powder, taken with cooked flour water, 2 qian (*Taiping Shenghui Fang*).
Corneal opacity in eyes: Gujing Cao and Saposhnikoviae Radix (Fangfeng) in equal parts. Ground into powder. Taken with rice drink, very effective (*Mingmu Fang*).
Post-varicella corneal opacity, feeling gritty with tearing, persisting for a long time: Use Gujing Cao ground into powder, dipped in persimmon or pig liver slices and eaten. Another method: Add Talcum Powder (Ge Fen) in equal parts, cook together inside a pig liver slice, eat daily. Another method: See Ye Ming Sha entry. (Shao Zhenren *Jiji Fang*)
Pediatric night blindness, sudden inability to see at dusk: Use one ram liver (do not wash with water, cut open with a bamboo knife), add a handful of Gujing Cao, cook in a clay pot, eat daily. Frequently effective. Avoid ironware. If unwilling to eat, roast until cooked, pound into pills the size of mung beans. Take 30 pills each time with tea (*Weisheng Jiaobao Fang*).
