Camellia (scientific name: Camellia? Species), also known as camellia, is the general name of many plants and horticultural varieties of Theaceae and Camellia. Petals are bowl-shaped and divided into single petals or double petals. Single-petal camellia is mostly primitive, and double-petal camellia can have up to 60 petals. Camellia has different degrees of red, purple, white and yellow flowers, and even camellias with color stripes. The highest flower branch can reach 4 meters. Sex likes warm and humid environment. The flowering period is long, from June 10 to May of the following year, and the full flowering period is generally from June1-March.
Extended data:
The efficacy of camellia: cooling blood and stopping bleeding; Removing blood stasis; Eliminate blood stasis and swelling. Main vomiting blood; Bleeding; Cough up blood; Bloody stool; Hemorrhoid blood; Red blood dysentery; Bloody; Blood collapse; Take it down; Scalding; Fall injury. Used for hematemesis, epistaxis, hematochezia and metrorrhagia; Topical treatment of burns, scalds and traumatic bleeding.
The efficacy of azaleas:
1, antitussive, antiasthmatic and expectorant effects: the antitussive effect of po5mg geranone in mice is equivalent to that of codeine 2mg, and ip geranone has the effect of resisting bronchospasm in guinea pigs caused by histamine. Rhododendron is the main effective component of Rhododendron Guanmu in treating tracheitis. Among the single symptoms, expectorant effect is the highest, followed by cough and asthma. A small amount of Chinese ink was injected into rabbit trachea, and its running speed was observed in vivo to determine the transport speed of mucus by tracheal cilia. Ip Rhododendron can obviously accelerate the transport speed, which accords with the clinical conclusion of eliminating phlegm.
2. Anti-inflammatory and bacteriostatic effects: Guaiaceae contained in this product has anti-inflammatory and uterus-stimulating effects, and can be used as an anti-inflammatory agent. Rhododendron has antibacterial activity against Staphylococcus aureus, MIC25ug/ml. Lilac acid and vanillic acid also have antibacterial and antifungal effects, and anisic acid also has antiseptic and antibacterial effects.
3, antihypertensive diuretic effect: Aralia toxin has antihypertensive effect on anesthetized cats iv. Although Polygonum aviculare has antihypertensive effect on anesthetized dogs, it lasts for a short time and is easy to produce rapid tolerance. Polydatin iv0.5mg/kg has diuretic effect on anesthetized dogs, and the effect is enhanced with the increase of dose. In the rat experiment, no matter whether po or IP is 34 mg/kg, it can produce obvious diuretic effect, which is not as strong as aminophylline, but its toxicity is only aminophylline 1/4, so its therapeutic index is larger.
