病
夫瘿瘤，皆因气血凝滞，结而成之。瘿则喜怒所生，多着于肩项，皮宽不急，捶捶而垂是也；瘤则随留
住，初作如梅李之状，皮嫩而光，渐如杯卵是也。瘿有五种，其肉色不变者，谓之肉瘿；其筋
脉现露者，谓之筋瘿；若赤脉交络者，名曰血瘿，若随忧恼而消长者，名曰气瘿；若坚硬而不可移者，名曰石瘿。
瘤亦有六种∶一曰骨瘤，二曰脂瘤，三曰肉瘤，四曰脓留，五曰血瘤，六曰石瘤。
瘿瘤二者，虽无痒痛，最不可决破，恐脓血崩溃，渗漏无已，必致杀人。其间肉瘤不可攻疗。

脂瘤、气瘤之类，当用海藻、昆布软坚之药治之。如东垣散肿溃坚汤亦可多服，庶得消散矣。

令气透贴之，痒则频贴。
一方加草乌、细辛、白芷。
Meiheqi (Plum-pit Qi) refers to a sensation of obstruction in the throat, where phlegm cannot be expectorated nor swallowed, feeling as if a plum pit is stuck there. It originates from excessive anger or joy, leading to accumulated heat and stagnation, which subsequently forms stubborn phlegm and qi constraint, causing this disease.
Treatment
The treatment should focus on guiding out phlegm, resolving constraint, clearing heat, and regulating qi. Herbs such as Chenpi (Tangerine Peel), Banxia (Pinellia Rhizome), Xiangfu (Cyperus Rhizome), Chuanxiong (Sichuan Lovage Rhizome), Shanzhi (Gardenia Fruit), Huangqin (Scutellaria Root), Zhike (Bitter Orange Fruit), and Suzi (Perilla Seed) may be used. If old phlegm is condensed and difficult to resolve, herbs with salty flavor that can soften hardness, such as Haishi (Fossilized Wood) and Liming, should be employed.

Disease
Yingliu (Goiter and Tumors) are all formed by the coagulation and stagnation of qi and blood. Ying (Goiter) arises from emotional disturbances like anger and joy, often appearing on the shoulders and neck, with loose skin that hangs down when tapped. Liu (Tumor) grows where pathogens remain; initially resembling a plum or apricot, the skin is tender and shiny, gradually enlarging to the size of a cup or egg. There are five types of Ying: those with unchanged flesh color are called Rouying (Flesh Goiter); those with visible veins are called Jingying (Sinew Goiter); those with intersecting red vessels are called Xueying (Blood Goiter); those that fluctuate with worry and anger are called Qiying (Qi Goiter); those that are hard and immobile are called Shiying (Stone Goiter).
There are also six types of Liu: Gu Liu (Bone Tumor), Zhi Liu (Fat Tumor), Rou Liu (Flesh Tumor), Nong Liu (Pus Retention/Tumor), Xue Liu (Blood Tumor), and Shi Liu (Stone Tumor).
Although Ying and Liu typically lack itching or pain, they must never be incised or ruptured, lest pus and blood collapse and leak endlessly, inevitably leading to death. Rou Liu (Flesh Tumor) should not be treated with aggressive methods.
Treatment
For Zhi Liu (Fat Tumor) and Qi Liu (Qi Tumor), herbs that soften hardness such as Haizao (Seaweed) and Kunbu (Kelp) should be used. Dongyuan's Sanzhong Kuijian Tang (Decoction for Reducing Swelling and Hardness) can also be taken frequently to promote resolution.
Formulas

Take one raw large Nanxing (Arisaema Rhizome), grind finely until sticky, add seven to nine drops of good vinegar to form a paste. For new lesions, use dried Nanxing ground into powder, mixed with vinegar to form a paste. First, prick the tumor surface with a small needle to allow qi penetration, then apply the paste. Apply frequently if itching occurs.
Another prescription adds Caowu (Aconite Lateral Root), Xixin (Asarum Root), and Baizhi (Angelica Dahurica Root).
