[Zhuye (Bamboo Leaf)]
Qi is neutral, flavor is pungent. Another view states it is bitter and greatly cold, with a pungent and neutral nature. Non-toxic.
*Bencao* records: It primarily treats cough with rebellious Qi, distension of tendons, acute foul sores, and kills small insects. It removes vexation and heat, wind-induced spasms, throat obstruction (Hou Bi), and vomiting. Zhongjing's Zhuye Tang uses Dan Zhuye (Light Bamboo Leaf).
*Xin* records: It removes vexation and heat, relaxes the skin, and benefits Qi.
*Zhen* records: It contains slight Yang within Yin, cooling the Heart Meridian.
[Cha / Ming (Tea)]
Qi is slightly cold, flavor is bitter.
*Bencao* records: It primarily treats vomiting and hiccups, warm Qi disorders, alternating chills and fever, hematemesis, and uterine bleeding (Beng Zhong). Distension of tendons.

*Bencao* records: It primarily treats phlegm-heat in the chest and cough with rebellious Qi.
*Yaoxing Lun* records: Dan Zhuye primarily treats hematemesis, wind caused by heat-toxin, suppresses toxicity from Danshi (mineral) drugs, and stops thirst.

It is suitable for stroke with coma or excessive sleepiness. Enters the Foot-Shaoyin and Hand-Shaoyin meridians. Ming (bitter tea), flavor is bitter and sweet, slightly cold. Non-toxic. It primarily treats sores, promotes urination, removes phlegm-heat and thirst. When used in decoctions for Yin-patterns, it helps overcome rejection of cold medicines. It also treats hidden Yang. The general idea is similar. Tea is bitter; the Classics state: "Bitter drains." Its nature moves downward, so how can it be said to clear the head and eyes?

Qi is cold, flavor is bitter. Non-toxic.
*Ye* records: It primarily treats dysentery with tenesmus and deficiency of the Lower Jiao. The Classics state: "Bitterness consolidates."

It is suitable for making a decoction to wash the eyes. Commonly known as Bai Mu. Take the bark, soak it in water until it yields a blue-green color. Using it together with Zicao (Arnebia Root) enhances the visual effect significantly. Daji is its guiding herb. It is incompatible with Wuzhuyu.
