☯ TCM Properties
Dispels Wind-Damp, relieves cough and dyspnea, relieves spasms and stops pain
Traditional Chinese Uses
Yang Jin Hua is the dried flower of Datura metel (Solanaceae), a pungent, warm, highly toxic herb entering the Lung and Liver channels. Traditionally it warms and quiets the Lung to relieve cough and wheezing in chronic asthma and cough without phlegm-heat, and it stops pain and spasm—used for epigastric and rheumatic pain and, in classical surgery, as an anesthetic. It also settles Wind and convulsions. Because its actives are the anticholinergic tropane alkaloids scopolamine, hyoscyamine, and atropine, the therapeutic dose is minute (roughly 0.3-0.6 g decocted, or 0.1-0.2 g in pills and powders). Overdose causes dry mouth, hot flushed skin, dilated pupils, blurred vision, rapid heartbeat, agitation, and delirium. It is contraindicated in pregnancy, glaucoma, hypertension, tachycardia, and in weak or feverish patients, and is dangerously confused with non-toxic Ling Xiao Hua (Campsis). Use only under strict medical supervision.

Botanical Description
Yang Jin Hua is the dried flower of Datura metel L. (Solanaceae), the downy thorn-apple or hindu datura, an erect annual or short-lived perennial herb 0.5 to 1.5 m tall with stout branching stems and broadly ovate, sinuate to entire leaves. The large solitary upward-facing trumpet-shaped flowers are 14 to 20 cm long, white to pale purple or yellow, single or double; the prickly globose capsule splits irregularly to release numerous flattened brown seeds. WARNING: All parts contain the tropane alkaloids hyoscyamine, scopolamine, and atropine and are highly toxic, producing anticholinergic delirium, mydriasis, tachycardia, hyperthermia, and in overdose death; the herb is a restricted drug in China and many countries. In traditional Chinese medicine the flower is acrid, warm, and toxic, entering the Lung and Liver channels; it stops cough and asthma, relieves pain, and calms convulsions, and was historically used as a surgical anesthetic.
