(Shi Cao [Lowland Herbs]) Tonifying Fire, Dispelling Cold, Eliminating Hernia
Huluba (Trigonellae Semen) [Specifically enters the Mingmen (Gate of Life)]. Bitter and warm in nature, it is purely Yang. It can also enter the Kidney to tonify the Mingmen fire. Therefore, medical texts record that it warms the Dantian (Elixir Field), strengthens the Primordial Yang, treats Kidney deficiency-cold, hernia, cold qi accumulation in Jia masses, unilateral descent of the Small Intestine, and cold-dampness gouty arthritis. (Li Shizhen stated: Huluba is a medicine for the Right Kidney and Mingmen. It is suitable for conditions where Primordial Yang is insufficient, cold qi lies latent, and fails to return to its source. The Song Dynasty "Huimin Heji Ju Fang" contains Huluba Wan, treating adult and pediatric cases of Small Intestine Ben Tun (rushing pig) hernia, unilateral descent, and abdominal masses resembling eggs with unbearable wandering pain up and down. The prescription uses 8 qian of Huluba, 6 qian of Fennel, 2 qian of Morinda officinalis root (processed, heart removed), 2 qian of Aconitum carmichaelii lateral root (processed, skin removed), 4 qian of Melia azedarach fruit (pits removed), and 5 qian of Evodia rutaecarpa. All are stir-fried, ground into powder, mixed with wine paste to form pills the size of wutong seeds. Take 15 pills per dose, washed down with salted wine.) Its efficacy is somewhat similar to Xianmao (Curculiginis Rhizoma), Fuzi (Aconiti Lateralis Radix Praeparata), and Liuhuang (Sulfur), but its strength ultimately falls short of Fuzi and Liuhuang. Therefore, to tonify fire, it must be combined with Fuzi, Liuhuang, Fennel, Evodia, and other herbs to be effective. It originates from overseas Huluo seeds, named so due to phonetic similarity. It is soaked in wine, dried in the sun, and stir-fried before use.
(Shan Cao [Mountain Herbs]) Tonifying Fire, Dispelling Cold, Dispersing Wind
Yinyanghuo (Epimedii Folium) [Specifically enters the Mingmen, concurrently entering the Liver and Kidney meridians]. Pungent, aromatic, sweet, and warm. Various texts record its ability to treat male impotence (Jue Yang bu xing) and female infertility due to Jue Yin (extreme yin deficiency). It also treats cold wind lao qi (chronic wasting syndrome), numbness and insensitivity of the four limbs, and weakness of the waist and knees. (Li Shizhen stated: Yinyanghuo has a sweet taste and fragrant aroma, is warm rather than cold, benefits essence and qi, and is a medicine for the Hand and Foot Yangming, Sanjiao, and Mingmen meridians. It is suitable for those with insufficiency of True Yang.) Presumably, because its flavor is sweet and warm, it tonifies fire and assists Yang; additionally, being pungent and aromatic, it dispels cold and scatters wind! Regarding the claim that long-term use leads to childlessness, it is likely due to excessive Yang leading to hypersexuality and subsequent depletion of essence and qi, with no other cause. (Tao Hongjing stated: Yinyanghuo is also known as "Yiri Baihe," presumably caused by consuming this herb.) Remove branches, stir-fry with sheep fat, use Dioscorea opposita (Shanyao) as an guiding herb, and combine with wine for better efficacy.
