The *Bie Lu* (Supplementary Records of Famous Physicians) states that Jing Mi Fructus (Cacumen Viticis, 蔓荆实) is indicated for wind-induced headache and tinnitus in the head. However, practitioners often find it ineffective. This is because people know Jing Mi as a pungent-cold herb, but fail to realize that its bitter-warm nature actually exceeds its pungent-cold property. The *Shen Nong Ben Cao Jing* (Divine Farmer's Materia Medica) records its flavor as bitter and slightly cold; the character "slightly" implies careful deliberation. The *Bie Lu* supplements with pungent, neutral, and warm properties, thereby revealing its complete nature. One should investigate this meaning thoroughly here. Chao Yuan-fang in the *Zhu Bing Yuan Hou Lun* (General Treatise on the Causes and Symptoms of All Diseases) states: Wind diseases of the head and face arise from bodily deficiency, where yang meridians are invaded by wind pathogens. All yang meridians ascend to the head and face. When physical exertion causes yang qi to dissipate, the cou li (skin pores) open, allowing wind invasion, which is termed "Shou Feng" (Head Wind). Since it mentions bodily deficiency and dissipation of yang qi, this clearly indicates wind invasion due to yang deficiency, rather than internal heat clashing with wind. In cases of yang deficiency, the branch manifestation is superior, while the root is inferior. However, treatment may target either the branch or the root; although the etiology is one, the syndromes differ. For those requiring root treatment, yang qi is weak and unassertive, with the foundation collapsing; for those requiring branch treatment, yang qi is lax and occasionally tilting, allowing minor pathogenic factors to occupy high positions. While treating the root may involve Tian Xiong Radix Aconiti Lateralis Preparata (Prepared Side Root of Monkshood), treating the branch is suitable for Jing Mi Fructus. Consider: if the headache were not caused by wind in the context of yang deficiency, why would there be tinnitus? Wind belongs to yang, whereas tinnitus due to yang deficiency belongs to yin. Jing Mi grows near water, and its fruit is black with spots, suggesting an affinity for the Kidney meridian. However, its aroma and flavor are pungent-cold combined with bitter-warm, and it acquires the qi transformation characteristics of the Taiyang (Greater Yang) meridian—cold at the root and hot at the branch. Thus, when used, it can reach yang from yin, transforming yin through yang. Its substance is light and void, ascending upward. Even for the cold-heat-damp bi syndrome and spasms between bones and sinews mentioned in the *Ben Cao Jing*, it can transform dampness to unblock bi obstructions. However, regarding the task of searching out and expelling pathogens, its nature is ultimately not enduring or potent enough, so ancient formulas rarely use it. It has specific expertise only in wind-induced headache and tinnitus. Cases of ineffectiveness occur simply because users do not observe correctly. I further reflect that awareness of Jing Mi's limitations is not new. Xu Zhicai stated it disperses wind-heat in the Yangming meridian, equating it indistinguishably with Bo He Herba Menthae (Mint) and Niu Bang Zi Fructus Arctii (Arctium Fruit). Zhang Jiegu (Zhang Yuansu) described it as yin within yang, but in reality, it is yang within yin; he claimed it cools blood in various meridians, but in fact, it is a qi-moving herb, not a blood-cooling herb. Those who still understood it include Li Binhu (Li Shizhen), who advocated its use for wind-deficiency of the head and face, and Zhang...
