常无小，贵者未常无大，盖人之阳物修伟者，因其肝气之有余；阳物细小者，由于肝气之不
足。以阴器为筋之余也，又属宗筋之会，肝气旺而宗筋伸，肝气虚而宗筋缩，肝气寒则阴器
缩，肝气热则阴器伸，是阳物之大小，全在肝经盛衰、寒热之故也。欲使小者增大，要非
补肝不可。然而肾为肝之母，心为肝之子，补肝而不补其肾，则肝之气无所生，补肝而不补
其心，则肝之气有所耗，皆不能助肝以伸其筋，助筋以壮其势，故必三经同补，始获其验矣

A small penis does not necessarily imply a lack of virility, nor does a tall stature guarantee it. Generally speaking, men with large and robust penises possess an excess of Liver Qi; those with small penises suffer from a deficiency of Liver Qi. Since the external genitalia are considered the surplus of sinews and represent the convergence of the "Zong Jin" (Major Sinews), when Liver Qi is vigorous, the Zong Jin extend; when Liver Qi is deficient, the Zong Jin contract; when Liver Qi is cold, the genitalia retract; and when Liver Qi is hot, the genitalia extend. Thus, the size of the penis depends entirely on the prosperity or decline, as well as the cold or heat conditions, of the Liver Meridian. To enlarge a small penis, it is essential to tonify the Liver. However, the Kidney is the mother of the Liver, and the Heart is the child of the Liver. If one tonifies the Liver without tonifying the Kidney, the Liver Qi will have no source for generation; if one tonifies the Liver without tonifying the Heart, the Liver Qi will be consumed. Neither approach can assist the Liver in extending its sinews or help the sinews to strengthen their momentum. Therefore, simultaneous tonification of these three meridians is required to achieve efficacy. The prescription used is *Duo Tian Dan* (Heaven-Stealing Pill):
Long Gu (Fossilized Bones, 2 liang), soaked in wine for three days, then soaked in vinegar for three days, and fired seven times. Use the previous wine and vinegar juices to soak the Donkey Kidneys (one pair, internal and external) boiled in wine for the duration of three incense sticks. Grind the Long Gu into powder, mix it into the Donkey Kidneys, and boil again for the duration of three incense sticks. Then add: Ren Shen (Ginseng Root, 3 liang), Dang Gui (Angelicae Sinensis Radix, 3 liang), Bai Shao (White Peony Root, 3 liang), Bu Gu Zhi (Psoraleae Fructus, 2 liang), Tu Si Zi (Cuscutae Semen, 2 liang), Du Zhong (Eucommiae Cortex, 3 liang), Bai Zhu (Atractylodis Macrocephalae Rhizoma, 5 liang), Lu Rong (Deer Antler Velvet, one piece, soaked in wine until permeable, sliced and cut into small pieces), Shan Yao Mai (Stemona Rhizoma, stir-fried), Wu Wei Zi (Schisandrae Fructus, 1 liang), Shu Di Huang (Rehmanniae Radix Praeparata, 3 liang), Shan Zhu Yu (Corni Fructus, 3 liang), Huang Qi (Astragali Radix, 5 liang), Fu Zi (Aconiti Lateralis Radix Praeparata, 1 liang), Fu Ling (Poria, 2 liang), Bai Zi Ren (Biota Seed, 1 liang), Sha Ren (Amomi Fructus, 5 qian), Di Long (Pheretima, 10 pieces).
Grind each ingredient into a fine powder. Mix with the juice of the Donkey Kidney and pound together. If the mixture is too dry, add honey and pound into pills. Take five qian each morning and evening, delivered with warm wine. Efficacy will be seen after one month of use. However, sexual abstinence must be maintained for two months, at least for seven periods of seven days. This ensures the penis becomes large and capable of prolonged intercourse, with ejaculation reaching far and conception being very easy. A man who has been childless for half his life may suddenly father a child; this is truly a miracle that steals the work of Heaven.
I, Chen Shiduo, transmit this prescription here, fearing not the taboo against revealing divine secrets, solely wishing that people for all generations may be spared the sorrow of having no heirs. However, those who receive my prescription should also act with reverence and focus on procreation. Do not indulge in frivolous sex or excessive desire. If you deplete your essence yourself, not only will you fail to conceive, but you will also suffer from Lao Zhai (Consumption/Tuberculosis). I shall not bear the blame for such negligence.
For this condition, *Zhan Yang Shen Dan* (Yang-Expanding Divine Pill) is also remarkably effective and is transmitted here as well.
Ren Shen (Ginseng Root, 6 liang), Bai Shao (White Peony Root), Dang Gui (Angelicae Sinensis Radix), Du Zhong (Eucommiae Cortex), Mai Dong (Ophiopogonis Tuber), Ba Ji Tian (Morindae Officinalis Radix) (each 6 liang); Bai Zhu (Atractylodis Macrocephalae Rhizoma), Tu Si Zi (Cuscutae Semen), Shu Di Huang (Rehmanniae Radix Praeparata) (each 5 liang); Rou Gui (Cinnamomi Cortex), Niu Xi (Achyranthis Bidentatae Radix), Bai Zi Ren (Biota Seed), Po Gu Zhi (Psoraleae Fructus) (each 3 liang); Long Gu (Fossilized Bones, 2 liang, processed with vinegar), Suo Yang (Cynomorii Herba, 2 liang), She Chuang Zi (Cnidii Fructus, 4 liang), Fu Pen Zi (Rubiae Fructus), Yin Yang Huo (Epimedii Folium) (each 4 liang); Lv Bian (Donkey Penis, one piece), Ren Bao (Human Placenta, one unit), Hai Ma (Seahorse, two pairs), Qiu Yin (Earthworm, 10 pieces), Fu Zi (Aconiti Lateralis Radix Praeparata, one piece), Rou Cong Rong (Cistanches Herba, one branch), Lu Rong (Deer Antler Velvet, one piece, processed normally).
Grind all ingredients into powder and form pills with honey. Take five qian daily, delivered with wine. Improvement will be seen after two months of use; by three months, the physique will become robust, allowing for prolonged intercourse and conception. However, conservation and care must be maintained for three months for efficacy; otherwise, there will be no result.
