【杏仁】
气味：气温，味甘，有小毒。
功效：主治咳嗽气逆，喉中痰鸣如雷，喉痹（咽喉肿痛闭塞），降气，产后乳疾及金疮（刀箭创伤）。寒性奔豚病。（注：用汤浸泡去皮尖、双仁者毒性极大，不可使用）
解析：
杏仁气温，禀受春天温和的木气，入足厥阴肝经。味甘，得大地中正的土味，入足太阴脾经。杏果本味苦，且属于核仁而带有小毒，因此禀受火性，入手少阴心经。其气味俱升，属阳。肺为金脏，气机上逆乘犯肺则引起咳嗽。肺厌恶气逆，急需食用苦味药以泄降肺气。杏仁味苦而下泄，所以能止咳。火邪结聚于喉部，闭塞不通，就形成喉痹。“雷鸣”是指火邪结聚、痰浊壅盛，声音如吼叫一般。杏仁温性能散结，苦性能下泄，甘性能缓急，所以主治这些病症。杏仁味苦能制约肺气，制约后则生化正常，使肺金之气下行，所以能降气。肝藏血，血得温则流行顺畅，所以主治产后乳疾。血液既已流通，疮口也能愈合，所以又主治金疮。心阳虚衰，则寒水之邪自下而上，像猪一样向上奔冲侵犯心君，这就称为寒水奔豚。杏仁之所以能主治此病，是因为它禀受火土的气味，能补益心阳而驱伐水邪。杏本有小毒，如果是双仁杏，则失去了常态，所以能致人死亡。
制方：
杏仁同白芍、甘草、北五味子、苏梗、百合、款冬花一起使用，治疗火逆气喘。单用一味杏仁，可消化狗肉积滞。
【桃仁】
气味：气平，味苦甘，无毒。
功效：主治瘀血，血闭，症瘕（腹内结块），邪气。杀小虫。（注：双仁者毒性极大）
解析：
桃仁气平，禀受秋天收敛的金气，入手太阴肺经。味苦甘且无毒，得大地中南方的火土之味，入手少阴心经、足太阴脾经。其气味降多于升，属阴。心主血，脾统血，血属阴，是有形之物，在周身周流，灌溉五脏。一旦有凝滞，不是瘀血就是血闭。到了有形可征的阶段就形成“症”，假借物象成形则成为“瘕”。这大概都是由于心脾运化功能失常的缘故。桃仁甘味能和血，苦味能散结，这样瘀血就能化解，血闭就能通畅，积滞就能消除。桃树是五木之精，能镇辟不祥之气，所以主治邪气。禀受火的苦味，所以能杀小虫。
[Apricot Seed]
Taste and Nature: Warm in nature, sweet in taste, slightly toxic.
Actions: Mainly treats cough with rebellious Qi (coughing and wheezing), roaring sounds in the throat, Hou Bi (sore throat with swelling and obstruction), descends Qi, postpartum disorders, and metal wounds (knife or arrow injuries). Cold Ben Tun (running piglet syndrome). (Note: Soak in decoction, remove skin and tips; those with double kernels are highly toxic and should not be used.)
Analysis:
Apricot seed is warm in nature, inheriting the mild Wood Qi of spring, entering the Foot Jueyin Liver Meridian. It is sweet in taste, obtaining the central Earth flavor of the earth, entering the Foot Taiyin Spleen Meridian. The apricot fruit is originally bitter, and as a kernel, it possesses slight toxicity, thus inheriting Fire properties, entering the Hand Shaoyin Heart Meridian. Its aroma and taste both ascend, belonging to Yang. The Lung is a Metal organ; when Qi rebels and attacks the Lung, it causes coughing. The Lung dislikes rebellious Qi and urgently requires bitter substances to drain it. Apricot seed is bitter and draining downward, hence it stops coughing. Fire結 (knots) in the throat, closing and blocking passage, resulting in Hou Bi. "Roaring" refers to fire knotting with phlegm obstruction, producing sounds like roaring. Apricot seed's warmth can dissipate knots, its bitterness can drain downward, and its sweetness can relieve urgency, thus treating these conditions. Apricot seed's bitterness controls Lung Qi; control leads to normal transformation and production, allowing Lung Metal Qi to descend, hence it descends Qi. The Liver stores Blood; when blood is warm, it flows smoothly, thus treating postpartum issues. Once blood flows, wound surfaces also heal, thus treating metal wounds. If Heart Yang is deficient, Cold Water pathogenic factors rise from below, rushing up like a piglet to invade the Heart Sovereign, known as Cold Water Ben Tun. Apricot seed treats this because it inherits Fire and Earth flavors, benefiting Heart Yang and attacking Water pathogens. Apricots have slight toxicity; if they have double kernels, they lose their normal state, hence they can cause death.
Prescription Formulation:
Apricot seed combined with Bai Shao (White Peony Root), Gan Cao (Licorice Root), Bei Wei Zi (Schisandra Berry), Su Geng (Perilla Stem), Bai He (Lily Bulb), and Kuan Dong Hua (Coltsfoot Flower) treats Fire-rebellious Qi asthma. Using a single ingredient of Apricot seed dissolves dog meat accumulation.
[Peach Kernel]
Taste and Nature: Neutral in nature, bitter and sweet in taste, non-toxic.
Actions: Mainfully treats blood stasis, blood closure, Zheng Jia (masses and accumulations), evil Qi. Kills small parasites. (Note: Those with double kernels are highly toxic.)
Analysis:
Peach kernel is neutral in nature, inheriting the gathering Metal Qi of autumn, entering the Hand Taiyin Lung Meridian. It is bitter and sweet and non-toxic, obtaining the Fire and Earth flavors of the south-central earth, entering the Hand Shaoyin Heart Meridian and Foot Taiyin Spleen Meridian. Its aroma and taste descend more than they ascend, belonging to Yin. The Heart governs Blood, and the Spleen controls Blood. Blood is Yin and has form; it circulates throughout the body and irrigates the five Zang organs. Any stagnation results in either blood stasis or blood closure. When it becomes tangible, it forms Zheng; assuming material form creates Jia. This is generally due to the failure of Heart and Spleen transportation. Peach kernel's sweetness harmonizes blood, and its bitterness dissipates knots; thus, stasis resolves, closure opens, and accumulations dissipate. The peach tree is the essence of the five woods, capable of suppressing and warding off inauspiciousness, thus treating evil Qi. Its bitterness, inheriting Fire properties, kills small parasites.
Prescription Formulation:
Peach kernel combined with Da Huang (Rhubarb Root), Po Xiao (Mirabilite), Gan Cao (Licorice Root), and Gui Zhi (Cinnamon Twig) is named Tao Ren Cheng Qi Tang (Peach Kernel Decoction to Order the Qi), treating Xu Xue (accumulated blood).
