CATDOLL : CATDOLL: Why is it difficult to promote wild cicada flowers on a large scale and why do we need to cultivate them artificially?

Why is it difficult to promote wild cicada flowers on a large scale and artificial cultivation is required?

High growth requirements.

Wild golden cicada flower has many benefits, a large market demand, and high economic value. However, wild golden cicada flower has very high requirements for the growth strips and it is difficult to promote it on a large scale. It needs to be artificially cultivated, but the cultivated products cannot meet the market demand.

How to eat Cordyceps sinensis flowers

The Cordyceps sinensis flowers can be directly soaked in water for drinking, used to make chicken soup, porridge, etc. They have high medicinal value.

Cicada fungus is a complex of the ergot fungus Penicillium parasitizing the nymph of the bamboo cicada. It is a cordyceps similar to Cordyceps sinensis. The wild cicada fungus native to the Hengduan Mountains and Tianmu Mountains, which infects the bamboo cicada, is called golden cicada fungus or big cicada grass.

The efficacy of cicada fungus has been recorded in the "Zhenglei Bencao" by Tang Shenwei in the Song Dynasty, and in the "Compendium of Materia Medica" by Li Shizhen in the Ming Dynasty and in the pharmacopoeias thereafter. The historical records of cicada fungus are earlier than those of cordyceps sinensis, but natural cicada fungus is very rare, and wild golden cicada fungus is even rarer and more precious, which limits its large-scale use.

Pharmacological Action

1. Anti-tumor effect: The anti-tumor effect of cicada fungus is to prevent the spread and metastasis of cancer cells by improving the patient's immunity. Director Lu Di of "China Cancer Treatment Protection Network" and tumor experts at home and abroad believe that the root cause of cancer is the decline of the patient's immunity.

2. Central nervous system regulation: Intraperitoneal injection of natural cicada fungus or artificial cultured dilute alcohol extracts into mice can significantly reduce their spontaneous activities, prolong the sleep time caused by sodium pentobarbital and chloral hydrate, and increase the sleep rate of mice given subthreshold hypnotic doses of sodium pentobarbital; it can also prolong the latency time of convulsions in mice induced by central nervous system stimulants strychnine and pentylenetetrazol.

3. Toxicity and side effects: Toxicity acute toxicity test shows that: natural cicada fungus ethanol extract was gavaged into mice at 60g/kg, and observed for 72 hours, and none of the 20 mice died. After administration, the animals only had reduced activity, and they all returned to normal after 24 hours. The LD50 of intraperitoneal injection is 12.5±2.1g/kg, and the toxic reaction is twisting, reduced activity, dyspnea and even death.

Cordyceps sinensis is a perennial insect-borne fungus. It is a complex of "worm" and "flower" formed after the bitter bamboo cicada is infected with Penicillium cicadae. It is also called "big cordyceps". The active ingredients and efficacy contained in it are similar to those of Cordyceps sinensis. The only difference is the medicinal properties. Cordyceps sinensis is cold in nature, while Cordyceps sinensis is warm in nature. They are suitable for basically the same population. Modern scientific research shows that Cordyceps sinensis can be used in the fields of proteinuria, chronic kidney disease, male dysfunction caused by kidney deficiency; pancreatic cancer, cervical cancer, gastric cancer, leukemia; insomnia; prevention and treatment of diabetes and its complications.

Paecilomyces cicadae (Miquel.)

Samson is a traditional precious Chinese medicine, cicada fungus, native to the Hengduan Mountains and the Tianbaipanpei Mountains. Wild cicada fungus infected with bitter bamboo cicadas is also called golden cicada fungus or big cicada grass (see Baidu Library Lu Di's "Golden Cicada Fungus"); Golden cicada fungus is an entomogenous medicinal fungus, which is an insect-fungus complex formed by the parasitism of Penicillium cicadae on the nymph of a certain Homoptera cicada family. The sexual form of cicada fungus is Cordyces cerevisiae.

cidadae shing.). There are relatively few cicada grasses in nature, and they are mainly insect-fungus complexes parasitized by Paecilomyces cidadae.

Golden cicada flower-morphological characteristics

Its roots are cicada pupae or mountain cicada larvae. The flowers grow from the heads of a single or 2-3 cicada larvae, about an inch long, and bloom and branch from the top. The asci grow from the front of the host body singly or in bundles of 2-3. It is 2.5-6cm long, hollow, and its stalk is cinnamon-colored.

, dark cinnamon color when dry, 1.5-4 mm in diameter, sometimes with small sterile branches with club-shaped heads

, cinnamon color, light rot color after drying, 7-28mm long, 2-7mm in diameter. The asci are buried in the asci seat, with a slightly protruding orifice, long oval, about 600μm×200μm. The ascospores are long cylindrical, 200-380μm×6-7μm. The ascospores are linear, with multiple transverse septa, and then break into single-cell segments of 8-16μm×1-1.5μm.

After drying, refrigerate and take out, soak and wash when needed

According to relevant research,

Cicada fungus is a biological pathological phenomenon, a complex of insects and fungi. In fact, the cicada nymphs are parasitized by the Cicada Pseudomonas cicadae and eventually die. The cicadas completely become the culture medium for the growth of the Cicada Pseudomonas cicadae, and eventually the nutrients of the cicadas are completely absorbed by the Cicada Pseudomonas cicadae. Therefore, what people call

"Cicada fungus" is the remainder after the mycelium, fruiting bodies and cicada nymphs of Paecilomyces cicadae are consumed.

Jinchongsui cicada fungus - the process of cicada fungus formation

Growth of cicadas: Cicadas lay eggs on tree branches, causing the branches to die. After a certain period of time, the eggs hatch into cicada nymphs. After a period of time, the cicada nymphs move underground to feed on the sap of plant roots. Cicada nymphs generally live underground for several years before they can crawl out of the soil, climb to a higher position, and emerge as cicada adults.

The formation of cicada fungus: before the cicada nymphs emerge from their pupae, they are infected and parasitized by the spores of Paecilomyces cicadae. When the living conditions are suitable, the hyphae begin to grow in large quantities and absorb the nutrients of the insect body. After a certain period of time, the cicada nymphs will die, and eventually the insect body will be completely occupied by the hyphae, leaving only an empty shell. When the climate is suitable, Paecilomyces cicadae transforms from the nutritional stage to the reproductive stage, and gradually the fruiting bodies of cicada fungus grow from the top of the entire mycelium. When the fruiting bodies mature, a lot of spore powder grows on the surface. The fruiting bodies of Paecilomyces cicadae often grow on the ground in the shape of flowers, hence the name cicada fungus.

Golden cicada flower - the function of cicada flower

Cicada fungus is a precious traditional Chinese medicine with high medicinal value. Natural cicada fungus (or golden cicada fungus) is mainly used in various compatibility medicines, nourishing medicinal diets or as a health product. Studies have shown that cicada fungus (Paecilomyces cicadae) contains a variety of effective ingredients such as polysaccharides, cordycepic acid, cordycepin, amino acids, various alkaloids, ergosterol and glycogen [3,4,5].

Song Yuliang et al. [6] used high performance liquid chromatography to determine that the adenosine content in cicada fungus was about 135 mg/g. Yu Ying et al. [7] studied the effect of high performance liquid chromatography on the adenosine content of cicada fungus Cordyces

cidadae (the sexual form of Paecilomyces cicadae) content was measured, and the results showed that it contained 39.35% total protein, 16 kinds of amino acids, mainly glutamic acid and aspartic acid, and also contained polysaccharides, fats and various trace elements, among which Mg was the highest.

Zhu Ying et al. [8] used spectrophotometry to measure the polysaccharide content in cicada fungus, which was 24.16

mg/g. Wen Lu et al. [9] determined the cordyceps active ingredients in cicada fungus and compared them with Cordyceps sinensis and Cordyceps militaris. The results showed that the cordycepic acid and adenosine contents of cicada fungus were higher than those of Cordyceps sinensis, and the polysaccharide and cordycepic acid contents were higher than those of Cordyceps militaris. It has similar medical and health care effects to Cordyceps militaris. Medical research has shown that cicada fungus has significant immune regulation, anti-fatigue, anti-tumor and kidney function improvement effects, and has achieved good therapeutic effects in clinical applications on tumors, chronic kidney disease, renal failure and other diseases. Professor Chen Yiping and others from Longhua Hospital Affiliated to Shanghai University of Traditional Chinese Medicine

Director Lu Di and others believe that Cicada Flower has good clinical efficacy in preventing further damage to chronic renal function, restoring renal function, and treating proteinuria [10,11]. Cicada Flower’s anti-tumor effects and prevention of cancer cell spread and metastasis are achieved by improving the patient’s immunity. Director Lu Di of the "China Cancer Treatment Protection Network" and authoritative tumor experts at home and abroad believe that the root cause of cancer is the patient’s decreased immunity. The immune system is the body’s own natural barrier that can produce anti-cancer and other immune protection effects to maintain the body’s physiological balance and stability. It can improve the tolerance of patients undergoing radiotherapy and chemotherapy to the toxicity of radiotherapy and chemotherapy, eliminate the severe pain unique to cancer, and reduce or eliminate the pain caused by radiotherapy and chemotherapy.

It can reduce side effects such as leukopenia, hair loss, loss of appetite, vomiting, etc., and improve cachexia, improve the quality of life, and prolong life.
