Pain resembling needle pricks belongs to the Heart Meridian (Heart Channel); intense fire and dryness cause severe pain in the eyeballs. One must abstain from alcohol, avoid spicy foods, and refrain from irritability and anger to prevent the condition from evolving and generating further complications. If the flowing fire is mild with only one point, and suddenly there is a needle-like pain in a specific area, one should prevent deterioration by clearing and diffusing the Ministerial Fire (Jun Huo), draining inflammation so that Ying Qi (Nutritive Energy) naturally becomes abundant.

This condition refers to eye pain resembling needle pricks. The disease resides in the Heart Meridian, representing a syndrome of excess Fire. If the pain suddenly appears in one or two spots, like needle pricks, even if the eyes are not red, it is still due to flowing fire of the Heart Meridian. By distinguishing which specific part hurts, one can see which meridian the pathogen is about to invade. Commentary: This condition often occurs in individuals with weak constitutions, eye fatigue, and concurrent strangury (Lin syndrome). When Ying Qi fails to flow upward to nourish the eyes, needle-like pain occurs; thus, nourishing Ying Qi is appropriate, whereas using methods to descend Fire would be too abrupt. It is suitable to take:

Jiajian Baze San (Modified Eight Corrects Powder) treats heart heat rushing to the eyes, causing redness, swelling, astringency, and pain, with hot tears and photophobia. It also treats evil heat in both the Greater and Lesser Heart meridians, all kinds of accumulated toxins, dry throat and mouth, excessive thirst with desire to drink, palpitations and facial heat, restlessness and irritability, cracked lips, epistaxis, mouth and tongue ulcers, sore and swollen throat, red and astringent urination, or urinary retention, as well as heat strangury and blood strangury. All these are suitable for treatment.

Hua Shi (Talcum), Gancao Shao (Terminal Licorice Root), Dahuang (Rhubarb Root and Rhizome, stir-baked wrapped in flour), Mutong (Akebia Stem), Qumai (Dianthus Herb), Cheqianzi (Plantago Seed), Zhizi (Gardenia Fruit, stir-fried), Xianhecao (Herba Siegesbeckiae, referred to here as Xu/Su) (all in equal parts, ground into powder).

Grind the above into fine powder. Take five qian per dose, with two zhong of water and thirty segments of Dengxincao (Juncus Effusus Pith), decoct until eight fen remains, remove the dregs, and take warm.

The Classics state: "Impaired function of the Bladder is called Long (urinary retention)." Therefore, it is proper to use Baze San to promote unblocking. Slippery substances remove adherence; Hua Shi (Talcum) and Cheqian (Plantago Seed) are slippery. Purging substances remove excess; Dahuang (Rhubarb Root and Rhizome), Gancao (Licorice Root), and Zhizi (Gardenia Fruit) are purgative. Unblocking substances remove stagnation; Qumai (Dianthus Herb), Xu (Siegesbeckia Herb), Mutong (Akebia Stem), and Dengxincao (Juncus Effusus Pith) are unblocking. For those with deficiency, Dahuang (Rhubarb Root and Rhizome) should not be used; instead, add Shengdihuang (Rehmannia Root), Sangbaipi (Mulberry Bark), and Ku Zhuye (Bitter Bamboo Leaf) to clear and treat.

Zi He (Zhang Zijian) said: Persistent headache indicates disease in the Three Yang meridians. Regarding the distribution of the Three Yang meridians, pain in the head and nape belongs to the Foot-Taiyang Bladder Meridian. Pain at Cuanzhu (BL2) is commonly known as supraorbital ridge pain. Pain in the upper lateral forehead, commonly known as hemianopia or migratory headache, belongs to the Foot-Taiyang Bladder Meridian (Note: Textual error likely exists in original, typically associated with Shaoyang). If the pain persists for a long time, it may lead to blindness. This is because disease in the Three Yang meridians is caused by retained phlegm in the chest and diaphragm. First, induce vomiting with Chatiao San (Tea Regulation Powder). After vomiting, administer Xinliang Qing Shang (Acrid-Cool Subduing Upper) herbs such as Chuanxiong (Szechwan Lovage Rhizome) and Bohe (Mint Herb). Shuhe (Wang Shuhe) stated, "When the Cun pulse is rapid and headache occurs," referring to this situation.
