可于方中加生硫黄三两。
胡桃（又名核桃）：味道微甜，气味芳香，性质温。含有大量油脂，将油榨出后，很快会变成黑色。它是滋补肝肾、强健筋骨的重要药物，因此善于治疗腰痛、腿痛以及一切筋骨疼痛。因为它能补肾，所以能坚固牙齿、使须发变黑，治疗虚劳引起的喘咳、气不归元（气息不能归根）、下焦虚寒、小便频数以及女子崩漏带下等各种证候。它的性质又能消散坚积、化瘀血，治疗心腹疼痛、砂淋、石淋、因堵塞引起的疼痛、肾衰不能过滤水分导致的小便不利。如果误吞铜器，多吃胡桃也能将其消化（尝试与铜钱一起咀嚼，铜钱即碎，可知其能化铜）。此外，它又善于消除疮疽及皮肤疥癣、头部的白秃，还能治疗毒邪深入骨髓导致的肢体软弱、无法行走。
【附案】有一个五岁的幼童，到了五岁还不会走路，身上多处生疮疡，治愈后又复发。得知他的父亲长期患有梅毒，这是遗传性的性病深在骨髓所致。为此开方，每剂药中使用胡桃仁八钱，辅以金银花、白鲜皮、土茯苓、川贝母、玄参、甘草等药物。这个方子稍作加减，服用二十多剂后，身上的疮疡全部痊愈，从此逐渐能够行走了。
附注：古方治疗虚寒引起的喘咳、腰腿酸痛，使用胡桃仁二十两捣烂研细，补骨脂十两酒蒸后研成粉末，用蜂蜜调得像饴糖一样稠，每天早晨用酒送服一大匙，不能饮酒的人用热水调服。汪昂认为，补骨脂属火，入心包和命门经，能补益相火以通达君火、温暖丹田、壮旺元阳；胡桃属木，能通达命门、利通三焦、温肺润肠、补养气血，有木火相生的奇妙作用。我常用此方治疗下焦虚寒的证候，确实有奇效。在上述方子中加入杜仲一斤，生姜炒蒜四两，共同制成丸药，名为青娥丸。治疗肾虚腰痛，而且此方不仅治疗肾虚腰痛，治疗虚寒引起的腿疼也极为有效。曾治疗一位六十多岁的老妇人，腿疼一年多不愈，她的双侧尺脉沉细，让她每天服用青娥丸，一个月后完全痊愈。如果是虚寒特别严重的，可以在方中加入生硫黄三两。
Walnut (also known as *Juglans regia*): Taste is slightly sweet, aroma is fragrant, nature is warm. It contains a large amount of oil; after the oil is pressed out, it turns black in a short time. It is an important herb for nourishing the Liver and Kidneys (*Zang-Fu organs*) and strengthening sinews and bones, thus it is effective in treating lower back pain, leg pain, and all types of pain in sinews and bones. Because it tonifies the Kidney, it can strengthen teeth, darken hair, and treat consumptive asthma and cough, Qi failing to return to its root, deficiency-cold of the Lower Jiao (*Lower Burner*), frequent urination, and various conditions such as metrorrhagia and leukorrhea in women. Its nature can also dissolve hardness and resolve blood stasis, treating epigastric and abdominal pain, sand strangury, stone strangury, pain caused by obstruction, and difficulty in urination due to kidney failure in filtering water. If copper objects are accidentally swallowed, consuming many walnuts can also digest them (try chewing with a copper coin; the coin will shatter, indicating its ability to dissolve copper). Furthermore, it is good at eliminating carbuncles and sores, skin scabies and tinea capitis (white baldness on the head), and can treat deep-seated toxic heat in the bone marrow causing weakness and inability to walk.
[Attached Case] A five-year-old child could not walk at age five, had multiple sores on his body that healed but recurred. Knowing his father had long suffered from syphilis, this was determined to be a hereditary venereal disease located deep in the bone marrow. A prescription was given using eight qian of Walnut Kernel per dose, assisted by Honeysuckle Flower (*Lonicerae Japonicae Flos*), White Peeling Bark (*Dictamni Cortex*), Smilax Rhizome (*Smilacis Glabrae Rhizoma*), Fritillaria Bulb (*Fritillariae Cirrhosae Bulbus*), Scrophularia Root (*Scrophulariae Radix*), and Licorice Root (*Glycyrrhizae Radix et Rhizoma*). With slight modifications to this formula, after taking more than twenty doses, all sores healed, and he gradually gained the ability to walk.
Note: Ancient formulas for treating deficiency-cold asthma/cough and soreness/pain in the waist and legs use twenty liang of Walnut Kernel, pounded into a paste, and ten liang of Psoralea Fruit (*Psoraleae Fructus*) steamed in wine and ground into powder. These are mixed with honey until thick like malt syrup, taken with one large spoonful with wine every morning; those who cannot drink alcohol take it mixed with hot water. Wang Ang stated that Psoralea belongs to Fire, enters the Pericardium and Mingmen (*Gate of Life*), tonifies Ministerial Fire to communicate with Sovereign Fire, warms the Dantian, and strengthens Original Yang; Walnut belongs to Wood, communicates with the Mingmen, benefits the Sanjiao (*Triple Burner*), warms the Lung and moistens the intestines, and nourishes Qi and Blood, possessing the wonderful effect of Wood generating Fire. I often use this to treat deficiency-cold of the Lower Jiao, and it indeed has miraculous effects. Adding one jin of Eucommia Bark (*Eucommiae Cortex*) and four liang of Ginger-fried Garlic to the above formula, processed into pills, named Qing'e Wan (*Qing'e Pill*). It treats Kidney deficiency lower back pain, and this formula is not only effective for Kidney deficiency lower back pain but also extremely effective for deficiency-cold leg pain. I once treated a woman over sixty years old who had suffered from leg pain for over a year without cure; her bilateral Chi pulses were deep and fine. She was instructed to take Qing'e Wan daily for over a month and was completely cured. For severe cases of deficiency-cold, three liang of native Sulfur (*Sulfur*) can be added to the formula.
