[Livistona chinensis / Olive Fruit]
Taste: Sour, Sweet. Nature: Warm. Non-toxic. Benefits the stomach and promotes the downward movement of Qi, generates body fluids and relieves thirst, eliminates diarrhea and resolves alcohol toxicity. Treats sore throat and resolves fish and crab poisoning.
Grows in Fujian, Guangdong, and other coastal areas. The tree is over one zhang (approx. 3.3 meters) high, with leaves resembling those of Zelkova or willow. Flowers in February, fruits in August; the fruit resembles a long date. When ripe, a wooden nail is inserted into it, causing the fruit to fall off naturally after one night.
[Areca Nut]
Taste: Bitter, Pungent. Nature: Warm, Astringent. Non-toxic. Directs Qi downward, aids digestion, expels water and resolves phlegm, promotes tissue regeneration and relieves pain, eliminates vexation and breaks stagnation. Treats distension and fullness of Hong Kong foot (Charcot joint/neuropathy), tenesmus after dysentery, Qi obstruction in urination and defecation, and swelling caused by Qi and water retention. Kills Taenia solium (pork tapeworm) and expels three types of parasites, treats various malaria cases and protects against miasma. Directs all Qi downward and eliminates various wind pathogens. Da Fu Zi (Areca Peel) has the same effects.
Grows in Lingnan, Jiaozhi, and Guang regions. The tree is five to seven zhang high, straight without branches, bark similar to Firmiana simplex, nodes similar to Cinnamomi Ramulus. Leaves grow at the top of the tree, resembling Musa balbisiana, with thorns on the sides like hawthorn spines. One fruit chamber contains hundreds of seeds, each with a shell.
For harm caused by phlegm-saliva, take as powder. (Verified Formula 1.)
For vomiting of phlegm-water, take together with Chen Pi (Citri Reticulatae Pericarpium). (Formula 2.)
For acid regurgitation and vomiting of water, use the above formula, taken with honey water. (Formula 3.)
For Shanghan (Cold Damage) with epigastric fullness, take as powder together with Zhi Shi (Aurantii Fructus Immaturus), administered with Huanglian Tang (Coptis Decoction). (Formula 4.)
For Shanghan with chest binding, decoct with wine and take. (Formula 5.)
For ascariasis colic and abdominal pain. Same as above. Abdominal pain with floating and surging pulse indicates parasitic pain. (Formula 6.)
For Taeniasis, take as powder. (Formula 7.)
[Areca Peel]
Wash with black soybean water, sun-dry, roast in ash, and slice for use. It is the peel of Da Fu Zi.
Taste: Pungent. Nature: Slightly Warm. Non-toxic. Resolves edema caused by water-Qi, eliminates upward rushing of various Qi; stops cholera and unblocks the intestines, regulates Hong Kong foot and eliminates epigastric fullness.
Originates from Lingbiao and Dianan. Similar to Areca Nut, it is a variety of Areca Nut, differing only slightly. Locally referred to generally as Areca Nut. The current usage is indeed Areca Nut peel.
[Sichuan Pepper Red]
Remove closed-mouthed ones.
Taste: Pungent. Nature: Warm. Toxic. Enters the Hand-Taiyin, Foot-Taiyin meridians, and the Right Kidney Mingmen. Warms the middle and disperses cold, dispels wind and removes dampness, directs Qi downward and expels water, aids digestion and removes bi-syndrome.
Stops cold cough and treats chronic dysentery, reduces edema and breaks masses, resolves gu-poison and kills roundworms, stops counterflow Qi and relieves abdominal pain. Treats flaccidity and numbness of the waist and legs, treats seminal emission and frequent urination, eliminates postpartum retained blood, stops joint pain due to wind. Strengthens teeth and hair, brightens eyes, promotes lactation, and eliminates scars. Sichuan Pepper Red has the same effects. (Refers to modern Sichuan pepper, with those from Shu/Sichuan being superior.)
