【桂枝】
气味温和。味道辛。无毒。主治上逆之气、咳嗽气逆。气结于喉导致的喉痹及呼吸异常（只呼不能吸）。通利关节。补益中焦、益气。长期服用可通达神明。
使身体轻盈、延缓衰老。
桂枝气味温和，禀受自然界春季和煦的木气，进入足厥阴肝经。味道辛、无毒，获得大地西方润泽的金味，进入手太阴肺经。其气味均具有上升特性，属于阳。肺是金的脏器，形体受寒或饮用冷水会损伤肺脏。肺受损则气不能下降，从而引发上逆之气和咳嗽。桂枝性温，能温暖肺脏，肺得温则气机下降，咳嗽气逆即可停止。所谓气结喉痹、呼吸异常，痹即闭塞之意。气结聚于咽喉，闭塞不通，只能呼气而不能吸气。桂枝辛温，能散结行气，则气结消散、闭塞通畅，不再出现只呼不吸的症状。辛味能润，能使筋脉调和而关节通利。中焦指脾。辛温之性能畅达肝气，从而使脾经受益，所以能补益中焦。益气是因为肺主气，肺脏温暖则真气流通而受益。长期服用能通达神明、使身体轻盈且不衰老，是因为长期服用可使心脏温暖以助阳气，阳气常伸张则精神灵明；阳气旺盛则身体轻盈、延缓衰老。

吴茱萸气味温和，禀受自然界春季和煦的木气，进入足厥阴肝经。味道辛、有小毒，获得大地西方燥烈的金味，进入手太阴肺经。其气味均具有上升特性，属于阳。中焦指脾，属太阴经。肺主气，也属太阴。气味温和则肺气令下行，太阴经亦温暖，所以能温中降逆。寒邪客居于胸腹，导致真气不通而疼痛。辛温之性能流行和散，所以能止痛。辛温暖肺，肺气通行，则水道通调，故又能除湿。血液凝涩则形成痹证，肝藏血，血得温则运行活泼，所以主治血痹。辛温属阳，具有发散作用，故能驱逐风邪。肺主皮毛并司管腠理，辛温疏散，腠理自然开泄。形体受寒、饮用冷水会损伤肺脏，肺受损则气不能下降，火气反而上逆，产生咳嗽气逆、寒热往来的症状。吴茱萸辛温暖肺，肺气下降，则寒热咳嗽气逆等症状自然平息。

[Cinnamon Twig]
The thermal nature is warm. The flavor is pungent. It is non-toxic. It primarily treats rebellious Qi, coughing, and wheezing; qi stagnation in the throat causing throat obstruction (bi) with abnormal respiration (exhaling but not inhaling); it benefits the joints, tonifies the Middle Jiao, and supplements Qi. Long-term administration connects to the spirit. It lightens the body and prevents aging.
Cinnamon Twig (Guizhi) has a warm thermal nature, inheriting the harmonious Wood Qi of spring from Heaven, entering the Foot Jueyin Liver Meridian. Its flavor is pungent and non-toxic, obtaining the moistening Metal flavor of the West from Earth, entering the Hand Taiyin Lung Meridian. Both its aroma and flavor ascend; it is Yang. The Lung is the organ of Metal. Cold damaging the form or cold drinks injuring the Lung causes the Lung to be damaged, resulting in Qi failing to descend, leading to rebellious Qi and coughing. Cinnamon Twig’s warm nature warms the Lung; when the Lung is warm, Qi descends, and coughing ceases. "Qi stagnation, throat obstruction, exhaling but not inhaling" refers to obstruction (bi), meaning blockage. Qi knots in the throat, blocking passage, allowing only exhalation without inhalation. Cinnamon Twig’s pungency and warmth disperse knots and move Qi; thus, knots scatter, blockages clear, and normal inhalation resumes. Pungency can moisten, harmonizing sinews and vessels, thereby benefiting the joints. The "Middle" refers to the Spleen. Pungency and warmth unblock Liver Qi, benefiting the Spleen Meridian, hence tonifying the Middle. Supplementing Qi occurs because the Lung governs Qi; when the Lung is warm, True Qi flows freely and benefits. Long-term use connecting to the spirit, lightening the body, and preventing aging happens because long-term use warms the Heart to assist Yang; constant extension of Yang brings spiritual clarity. Abundant Yang leads to a light body and prevention of aging.
Formulation:
Cinnamon Twig combined with White Peony Root (Baishao), Licorice Root (Gancao), Fresh Ginger (Shengjiang), and Jujube (Dazao) is named Guizhi Tang (Cinnamon Twig Decoction). It treats Wind Strike (Zhongfeng). Combined with White Peony Root, Licorice Root, Maltose (Yitang), Fresh Ginger, Jujube, and Astragalus Root (Huangqi), it is named Huangqi Jianzhong Tang (Astragalus Decoction for Establishing the Middle). It treats Yin-Blood deficiency.
[Evodia Fruit]
The thermal nature is warm. The flavor is pungent. It has slight toxicity. It primarily warms the Middle, directs Qi downward, stops pain, dispels Dampness and Blood Bi, drives out Wind pathogenic factors, opens the Cou Li (pores/skin texture), and treats coughing, wheezing, chills, and fever. (Use after soaking and roasting.)
Evodia Fruit (Wuyu) has a warm thermal nature, inheriting the harmonious Wood Qi of spring from Heaven, entering the Foot Jueyin Liver Meridian. Its flavor is pungent with slight toxicity, obtaining the dry and fierce Metal flavor of the West from Earth, entering the Hand Taiyin Lung Meridian. Both its aroma and flavor ascend; it is Yang. The Middle refers to the Spleen, which belongs to the Taiyin Meridian. The Lung governs Qi and also belongs to Taiyin. Warm thermal nature causes Lung Qi to descend, warming the Taiyin Meridian, thus warming the Middle and directing Qi downward. When Cold pathogenic factors lodge in the chest and abdomen, True Qi becomes blocked, causing pain. Pungency and warmth promote circulation and dispersion, thus stopping pain. Pungency and warmth warm the Lung; as Lung Qi circulates, water passages regulate, thereby dispelling Dampness. Stagnant Blood forms Bi; the Liver stores Blood, and warm Blood moves actively, thus treating Blood Bi. Pungency and warmth are Yang, possessing dispersing properties, thus driving out Wind pathogenic factors. The Lung governs skin/hair and controls Cou Li; pungency and warmth disperse, naturally opening the Cou Li. Cold damaging the form and cold drinks injuring the Lung causes Qi to fail to descend, while Fire rebels upward, generating symptoms of coughing, wheezing, chills, and fever. Evodia Fruit’s pungency and warmth warm the Lung; as Lung Qi descends, symptoms of chills, fever, coughing, and wheezing naturally subside.
Formulation:
Evodia Fruit combined with Ginseng Root (Renshen), Fresh Ginger, and Jujube is named Wuyu Tang (Evodia Decoction). It treats vomiting of saliva/phlegm and headache. Combined with Tangerine Peel (Chenpi) and Aconite Root (Fuzi), it treats hiccups caused by rebellious Kidney Qi. Combined with Coptis Rhizome (Chuanlian) and White Peony Root as pills, it treats dysentery. Taken with one qian of decocted Prepared Ginger (Paojiang) powder, it treats acid regurgitation immediately after eating. Combined with Cinnamon Bark (Rougui) and Prepared Ginger as pills, named Hezhong Wan (Harmonize the Middle Pill), it treats abdominal distension due to Cold.
