Traditional Chinese Uses

Qian Ri Hong is the flower (or whole plant) of Gomphrena globosa, globe amaranth, a sweet, neutral herb entering the Lung and Liver channels. In its Lung aspect it stops cough and calms wheezing, being a folk remedy for chronic cough, whooping cough, bronchitis and asthma, where it helps resolve Phlegm and clear the airways. In its Liver aspect it clears Liver Heat, subdues rising Liver Yang and brightens the eyes, used for headache, dizziness, red painful eyes and heat-type dysentery, and it resolves toxicity for sores and boils.

It is usually prepared as a light decoction or floral infusion (about 3–9 g of the flower). Some sources caution its use in certain asthmatic patients, so it should be applied according to pattern.

Botanical Description

Qian Ri Hong is Gomphrena globosa L. (Amaranthaceae), globe amaranth or 'thousand-day red,' an erect, branching annual herb 20-60 cm tall, native to Central and South America and now widely naturalized and cultivated as an ornamental across southern China. Stems are slender, hairy, and often reddish at the nodes; the opposite, oblong-elliptic to obovate leaves are 3-10 cm long, entire, and pubescent. At each branch tip stands a single globose to ovoid inflorescence 1.5-3 cm across, composed of densely packed papery bracts in vivid magenta, purple, pink, or white, each subtending a small inconspicuous true flower; the bracts retain their color long after drying, hence the Chinese name. The dried flower heads are used in folk Chinese medicine for chronic cough, asthma, whooping cough, sore eyes, headache, and dysentery, and are commonly brewed as a tisane. The species shows mild bronchodilatory and antitussive activity in pharmacological studies.

Active Constituents

Gomphrenin I (betanidin 6-O-beta-glucoside)

Betacyanin (betalain pigment)

Concentration: One of eight betacyanins quantified by HPLC with diode-array detection in extracts of the inflorescence, the part used as the drug

The parent betacyanin of this species and the compound that gives the flower head its violet-red colour. Structure established by nuclear magnetic resonance and ion-spray mass spectrometry on material isolated from G. globosa flowers. It is a pigment and antioxidant; no respiratory activity has been demonstrated for it.

Gomphrenin II (betanidin 6-O-[6'-O-(E-4-coumaroyl)-beta-glucoside])

Acylated betacyanin (coumaroyl ester)

Concentration: Detected among the eight betacyanins of the inflorescence; not individually quantified in the drug

The 4-coumaroylated form of gomphrenin I. Acylation raises pigment stability, which is why the flower is used as a food colourant, but confers no separately documented pharmacology.

Gomphrenin III (betanidin 6-O-[6'-O-E-feruloyl-beta-glucoside])

Acylated betacyanin (feruloyl ester)

Concentration: Together with isogomphrenin III, one of the two major betacyanins in a betacyanin-rich extract of the inflorescence

The feruloylated betacyanin and, with its isomer isogomphrenin III, the dominant pigment of the drug. Contributes to the strong in vitro scavenging of reactive species, particularly superoxide radical, reported for inflorescence extracts.

Isogomphrenin III

Acylated betacyanin (C-15 epimer of gomphrenin III)

Concentration: Major metabolite of the betacyanin-rich inflorescence extract alongside gomphrenin III

The C-15 epimer of gomphrenin III and co-dominant pigment. Both epimers decarboxylate on heating, so a hot floral infusion, the way the drug is normally taken, does not contain the same molecular species as a cold extract.

Kaempferol-3-O-(6-rhamnosyl)hexoside and kaempferol-3-O-hexoside

Flavonol O-glycosides

Concentration: The main phenolic compounds of the inflorescence; the decoction carried the highest total phenolic content of three extract types tested

The principal non-pigment phenolics of the flower head, and the constituents most concentrated by the traditional preparation method, since decoction outperformed the other extracts. Inflorescence extracts reduced nitric oxide output in lipopolysaccharide-stimulated RAW 264.7 macrophages, an anti-inflammatory signal at the cell level only.

Clinical Studies

Phytochemical investigations and biological potential screening with cellular and non-cellular models of globe amaranth (Gomphrena globosa L.) inflorescences

Silva LR, Valentao P, Faria J, Ferreres F, Sousa C, Gil-Izquierdo A, Pinho BR, Andrade PB (2012) Food Chemistry in vitro Verified: In vitro / animal

The only substantive pharmacological study on the correct plant part. Twenty-four phenolic compounds and eight betacyanins were determined by HPLC with diode-array detection across three extracts of the inflorescence. The decoction carried the most phenolics, dominated by kaempferol-3-O-(6-rhamnosyl)hexoside and kaempferol-3-O-hexoside; the betacyanin-rich extract was dominated by isogomphrenin III and gomphrenin III. Extracts reduced nitric oxide in lipopolysaccharide-stimulated RAW 264.7 cells and scavenged reactive species strongly, especially superoxide. Cell and chemical assays only; nothing here tests the traditional cough or wheezing indication.

Historical Texts

Hua Jing (Chen Haozi)

Qing dynasty, 1688
The earliest Chinese text to record Qian Ri Hong. It is a horticultural manual rather than a materia medica, which is consistent with the plant's history: Gomphrena globosa is native to tropical America and reached China only in the seventeenth century, so it is absent from every classical bencao including the Ben Cao Gang Mu.

Zhi Wu Ming Shi Tu Kao (Wu Qijun)

Qing dynasty, 1848
Describes the plant in terms that match the modern Gomphrena globosa, fixing its botanical identity. Its medicinal use in China, for cough, wheezing and clearing the Liver, is therefore a late and largely folk development rather than a classically transmitted indication, and the published research does not yet test it.
