琥珀感木、土之气而兼受火气炼化，因此味苦，性平，无毒，颜色赤红，属于阳中微阴，性质沉降。它主要归入手少阴心经和手太阳小肠经，同时也进入足厥阴肝经。专入血分，所以能破除痈肿、消除瘀血，通利水道、治疗淋证，其能够安定五脏、镇摄魂魄的原因在于：五脏藏神，若受到外邪感触，则神志不安；琥珀能驱杀精魅鬼邪，因此五脏得安、魂魄得定，况且琥珀本身禀赋就有安神的特性！
琥珀入药时，需研成粉末，用汤剂调服以通利水道，治疗五种淋证，镇摄魂魄，安定五脏，破除凝结的瘀血，驱杀鬼魅精邪，止血生肌，明目去翳，治疗产后血晕及儿枕痛（产后腹痛），治愈溃烂的金疮（金属利器造成的创伤），以及胃脘痛。茯苓生于阴而成于阳，禀受天地之气的时间较短，只可治气病而安心利水；琥珀生于阳而成于阴，禀受天地之气的时间较深，故能治血病而镇心安神化气，其药性比茯苓更峻烈，对于火炎水涸（阴虚火旺）者禁用。配合辛温药物使用，则能行血破血；配合淡渗利湿药物使用，则能通利窍道、行水；配合重镇堕胎或安神药物使用，则能镇心安神。但琥珀终究具有消磨渗利的药性，对虚人不利，内热阴虚、小便不利者，若服用此药强行利尿，会导致真阴更加耗损。
主治（参考《痘疹合参》）：治疗痘疹后出现的惊风，以及小便不利，起到宁神镇惊的作用。
按语：琥珀感受木、土之气，并兼受火气炼化，因此对脾土有功，脾能运化，肺金下降，小便自然通畅。如果是因为血少而导致小便不利的情况，误用琥珀，反而会导致燥急的痛苦。
蔓荆子禀受阳气而生，兼得金气炼化而成，味苦、辛，微温，无毒。其气清轻、味淡薄，性质浮升并属阳。它进入足太阳膀胱经、足厥阴肝经，兼入足阳明胃经。因其苦温辛散，所以主要治疗风寒湿热之邪，以及这三条经脉所受的病症。蔓荆子主要治疗筋骨间的寒热、湿痹引起的拘挛，调理经络头痛、流泪、头沉昏闷，通利关节、止脑鸣。它能通利九窍，驱虫、散风湿，明目，使松动的牙齿变得坚固，胃虚者禁止服用，否则会产生祸患、生痰；血虚头痛者，使用蔓荆子也可能使病情加重。
Amber (Hupo) is influenced by the Qi of wood and earth, combined with the transformation of fire; therefore, it tastes bitter, is neutral in nature, non-toxic, and red in color. It belongs to yang with a slight yin quality and has a descending property. It enters the Hand Shaoyin (Heart) and Hand Taiyang (Small Intestine) meridians, and also the Foot Jueyin (Liver) meridian. It specifically enters the blood level, thus capable of breaking abscesses, resolving stasis, promoting urination, and treating strangury. Its ability to calm the five zang organs and stabilize the soul/hun and po lies in the fact that the five zang organs store the spirit; when disturbed by external pathogens, the spirit becomes unsettled. Amber can expel evil spirits and malevolent entities, thereby calming the five zang organs and stabilizing the soul/hun and po. Moreover, its inherent nature possesses sedative properties!
When used medicinally, Amber is ground into powder and taken with decoction to promote urination, treat the five types of strangury, stabilize the soul/hun and po, calm the five zang organs, break凝 clotted blood, expel evil spirits and malevolent entities, stop bleeding, generate flesh, brighten the eyes, remove nebulae, treat postpartum blood syncope and epigastric pain due to retained lochia (Erzhen Tong), heal ulcerated traumatic wounds from metal instruments, and treat epigastric pain. Poria (Fuling) is born in yin and matures in yang, having received heaven and earth qi for a short time; it can only treat qi disorders to calm the heart and promote urination. Amber is born in yang and matures in yin, having received heaven and earth qi for a long time; thus, it can treat blood disorders, settle the heart, and transform qi. Its potency is stronger than that of Poria, and it is contraindicated in cases of hyperactive fire drying up fluids (Yin deficiency with fire hyperactivity). Combined with acrid-warm herbs, it moves and breaks blood; combined with bland-leaching herbs, it opens orifices and promotes water metabolism; combined with heavy-settling or abortifacient herbs, it settles the heart and calms the spirit. However, its nature is ultimately dissipating and leaching, which is unfavorable for deficient persons. In cases of internal heat, Yin deficiency, and difficulty in urination, using this herb to forcibly promote diuresis will further deplete true Yin.
Main indications (referencing *Douzhen He Can*): Treats convulsions after smallpox/variolae, as well as difficulty in urination, acting to calm the spirit and subdue fright.
Note: Amber receives the Qi of wood and earth, combined with the transformation of fire, thus benefiting the Spleen Earth. When the Spleen can transport and transform, and Lung Metal descends, urination naturally flows freely. If difficulty in urination is caused by blood deficiency, mistaken use of Amber will instead cause suffering from dryness and urgency.
Vitex Fruit (Manjingzi) is born receiving Yang Qi and matures through the transformation of Metal. It tastes bitter and acrid, is slightly warm, and non-toxic. Its Qi is clear and light, its taste thin, and its action floats upward, belonging to Yang. It enters the Foot Taiyang (Bladder), Foot Jueyin (Liver), and additionally the Foot Yangming (Stomach) meridians. Due to its bitter-warm and acrid-dispersing nature, it primarily treats pathogenic factors of wind-cold, damp-heat, and diseases affecting these three meridians. Vitex Fruit mainly treats cold-heat in muscles and bones, spasms and contractures due to damp-bi, regulates channel headaches, tearing, heaviness and dizziness of the head, benefits joints, and stops tinnitus/cranial buzzing. It unblocks the nine orifices, expels parasites, disperses wind-damp, brightens the eyes, strengthens loose teeth, is contraindicated in Stomach deficiency (as misuse causes disaster and phlegm generation), and may exacerbate headache in cases of blood deficiency.
Main indications (referencing *Douzhen He Can*): Should be soaked in wine and sun-dried. Used to reduce swelling on the face and head from pustules, as well as wind-induced headache, cranial buzzing, tearing, and internal pain of the eyeballs.
