【芎（川芎）】
【危害】其药性辛散，易耗泄人体真气。药力上行至头部和眼部，下行至血海（指冲脉或肝脏藏血之处）。凡是患有气机上逆、痰多气喘、虚火上炎、呕吐、呃逆、自汗、容易出汗、盗汗、咽喉干燥口舌燥渴、骨蒸潮热、口渴烦躁等症状的患者，以及气弱体质的人，都不宜使用。单独服用并长期服用，会导致人突然死亡，这也是因为耗泄了真气的缘故。川芎畏惧黄连和硝石，厌恶黄芩和山茱萸。
【功效】味辛性温，具有升浮之性，归心包经、肝经、胆经和三焦经。能滋润肝燥，补益肝虚，是血分中的气药。能提升清阳之气而开通各种郁结，用于搜风、散瘀、止痛、调经。个头较小的称为“抚芎”，能止痢疾、开郁结，这是依靠其上升和辛散的力量。以白芷为引经药，可抑制雌黄的毒性。
【炮制与采集】八月时根部开始结出块茎，此时才可以挖掘取出并晾晒干燥。凡入药使用，以四川产的大块根，内部颜色洁白且不油腻，咀嚼时味道微辛甘者为佳，需用酒炒制。其嫩苗可做蔬菜食用，气味很香，俗称香芹菜。我在西北道路上曾吃过它。
【苦楝子】
【别名】一名苦楝子
【危害】味苦性寒，如果脾胃虚寒者，绝对禁忌使用。
【功效】味苦性寒，能引导小肠和膀胱的热邪下行，从而牵引心包相火下降，通利小便，是治疗疝气的要药。也用于治疗伤寒引起的热厥腹痛，治疗疮疥，杀灭三种寄生虫。以茴香为引经药。苦楝的根皮性微寒，能杀灭各种寄生虫，通畅大肠，采收时间没有固定限制。
【炮制与采集】苦楝子，以四川产的品质优良。十二月采收后，熬干后用酒拌润，蒸软后去掉皮和核，取果肉使用。凡是用肉就不用核，用核就不用肉；如果使用核，需捣碎后使用。近来只用酒炒，也有去掉果肉只取树皮使用的，这样苦寒的性质就会减弱。果实形状像小铃铛，成熟后呈黄色，所以名叫金铃子。
【赤芍药】
【危害】赤芍能破血，凡是所有血虚病症，以及腹泻产后、恶露已经排尽、少腹疼痛已经停止、痈疽已经溃破的情况，都不宜服用。赤芍厌恶芒硝、石斛和鳖甲，畏惧龟甲和小蓟。与藜芦相反。
【功效】味苦酸，性微寒，能泻肝火，专门运行恶血，兼能利小肠。治疗腹痛、胁痛、坚硬积块、血痹、疝瘕、经闭、肠风、痈肿、目赤。能在土中泻木（即通过泻脾土来平抑肝木），赤色能发散邪气，能行血中之滞涩。以雷丸为引经药。
【炮制与采集】分株移栽时，根部气味最为浓烈，在八九月挖掘取出，切片后用酒炒制，单瓣的红芍药用于入药。
[Chuanxiong (Ligusticum Chuanxiong)]
[Harm] Its nature is acrid and dispersing, prone to depleting the true Qi. It ascends to the head and eyes, and descends to the Blood Sea (referring to the Chong Mai or the Liver's function of storing blood). For any condition involving ascending Qi, phlegm and wheezing, deficiency fire flaming upward, vomiting, hiccups, spontaneous sweating, easy sweating, night sweats, dry throat and mouth, bone-steaming tidal fever, thirst and irritability, as well as for those with weak Qi constitution, it is not suitable for use. Taking it alone for a long time can cause sudden death, which is also due to the depletion of true Qi. It fears Coptidis Rhizoma (Huanglian) and Natrii Sulfas (Xiaoshi), and dislikes Cornus Officinalis Fructus (Shanzhuyu).
[Benefit] Acrid and warm in nature, ascending and floating, entering the Pericardium, Liver, Gallbladder, and Sanjiao channels. It moistens Liver dryness and supplements Liver deficiency; it is an Qi-moving herb within the Blood category. It raises clear Yang and opens various stagnations, serving to search out wind, dissipate stasis, relieve pain, and regulate menstruation. The smaller ones are named "Fuxiong," capable of stopping dysentery and opening depression, relying on their ascending and acrid-dispersing power. Angelicae Dahuricae Radix (Baizhi) serves as the guiding herb, suppressing the toxicity of Orpiment (Ciyellow).
[Processing and Collection] In August, when the rhizomes begin to form at the root base, they can be dug up and sun-dried. For medicinal use, large pieces from Sichuan that are white inside, not oily, and taste slightly acrid and sweet when chewed are considered best; they should be stir-fried with wine. The young shoots can be eaten as vegetables and are quite fragrant, commonly known as Fragrant Celery. I have eaten them on roads in the northwest.
[Koulianzi (Melia Toosendan Fruit)]
[Alias] Also known as Kuxianzi.
[Harm] Bitter and cold in nature; strictly contraindicated for those with Spleen and Stomach deficiency-cold.
[Benefit] Bitter and cold in nature, it can guide heat from the Small Intestine and Bladder downward, thereby drawing down the Ministerial Fire of the Pericardium, promoting urination, and serving as a key herb for treating hernia. It is also used to treat abdominal pain caused by cold-heat reversal in Cold Damage disorders, sores and scabies, and to kill three types of parasites. Foeniculum Vulgare Fructus (Huixiang) serves as the guiding herb. The bark of the root has a slightly cold nature, kills various parasites, and unblocks the Large Intestine; it can be collected at any time.
[Processing and Collection] Koulianzi, those from Sichuan are of superior quality. Collected in December, dried by heating, mixed with wine, steamed until soft, then the skin and seeds are removed, using only the flesh. Generally, if using the flesh, do not use the seeds; if using the seeds, do not use the flesh. If using the seeds, crush them before use. Recently, only wine-stir-frying is used. Some remove the flesh and use only the bark, which reduces its bitter-cold nature. The fruit resembles a small bell, turning yellow when ripe, hence the name Jinlingzi.
[Chi Shaoyao (Red Peony Root)]
[Harm] Chi Shaoyao breaks blood stasis. It is unsuitable for all conditions of Blood deficiency, as well as for postpartum cases with diarrhea, after lochia has ceased, after lower abdominal pain has stopped, and after carbuncles and ulcers have ulcerated. It dislikes Mirabilite (Mangxiao), Dendrobii Caulis (Shihu), and Testudinis Carapax et Plastrum (Biejia); it fears Testudinis Carapax (Guijia) and Paeoniae Thunbergii Herba (Xiaoji). It is inversely compatible with Veratrum Nigrum Rhizoma (Lilu).
[Benefit] Bitter and sour, slightly cold in nature. It clears Liver Fire, specifically moves foul blood, and benefits the Small Intestine. It treats abdominal pain, hypochondriac pain, hard accumulations, blood obstruction, hernia masses, amenorrhea, intestinal wind, abscesses and swellings, and red eyes. It can drain Wood through Earth (draining Spleen Earth to subdue Liver Wood); the red color disperses pathogenic factors, and it can move stagnation within the blood. Omphalia Lapidea (Leiwan) serves as the guiding herb.
[Processing and Collection] When divided and transplanted, the roots have the strongest aroma. They are dug up in August or September, sliced, and stir-fried with wine. Single-petaled Red Shaoyao is used for medicinal purposes.
