The efficacy and function of Peach Ear Seven

Traditional Chinese medicine culture is profound and extensive, and Chinese medicinal materials account for a large proportion of it. Do you know about Taoerqi? What are its effects and functions, and how to eat it? I believe many people are very interested in it. Let me tell you one by one below.

[Other names] Copper chopsticks (Shaanxi Chinese Herbal Medicine), small-leaf lotus (Commonly Used Chinese Herbal Medicines in Tibet), chicken moss (Gansu Health Newsletter (4): 37, 1972), Olemoselomajongwa (Tibetan name).

[Source] It is the root and rhizome of Podophyllum , a plant of the Berberidaceae family. Harvest from July to August.

[Original morphology] Perennial erect herb, 40 to 80 cm tall. The stem is green, smooth and ridged, with 2 to 3 leaves on the upper part. The leaves are shield-shaped, with straight stems up to 25 cm long, palmately 3-parted, several lobes to the base, and the lobes are further lobed to the middle, green, smooth on the upper side and hairy on the lower side. The flowers are solitary in the leaf axils, red; the bracts are lanceolate; the corolla has 6 petals, the outer 3 petals are longer, 4.5 cm long, and the inner 3 petals are smaller; there are 6 stamens; the stigma is multi-lobed. The berries are oval in shape and red in color. Seeds numerous, with aril. Flowering period is from April to May.

[Habitat distribution] It grows in shady and moist places under forests in Zhongshan area. Distributed in Sichuan, Shaanxi, Gansu, Qinghai, Yunnan, Tibet and other places.

[Properties] The rhizome is short and thick, reddish brown or light brown; the roots are thin and long, 15 to 25 cm long, about 2 mm thick, curved at the rhizome, light brown or brownish yellow on the surface, with fine longitudinal wrinkles, and attached with curled thin fibrous roots. The cross section is round and yellowish white. It has a pungent smell and a bitter taste.

[Chemical composition] Four components were isolated from the root: podophyllotoxin; C21H22O2, melting point 122~4℃; quercetin, melting point 308~10℃; delphinidin.

[Pharmacological action] In the early years, it was reported that podophyllin has a similar inhibitory effect on mitosis as colchicine on rabbit cells and human skin. Later, the liposome-podophyllotoxin was isolated, which can inhibit cell mitosis in the middle stage and has a significant inhibitory effect on animal tumors, but has a low therapeutic index, is highly toxic to humans, and has no medicinal value. Later, lignans with anti-cancer effects were isolated one after another, but they were still highly toxic and not suitable for systemic application. Its derivatives such as podophyllotoxin (SP-I) are currently used clinically. They are less toxic and do not damage the hematopoietic system. They can be used to treat solid tumors or combined with surgery and radiotherapy. They are effective for breast cancer, bladder cancer and skin cancer. The benzyl derivative of podophyllotoxin, SP-G, is less toxic and can be applied topically to treat tumors of the ear, nose, and pharynx. Another derivative of podophyllum lignans, VM-26, is also less toxic. It can not only terminate nuclear mitosis, but also prevent cells from entering the division phase, leading to rapid cell lysis. Low concentrations can inhibit the binding of thymine to DNA. It is effective for advanced lymphoreticular cell sarcoma, and its side effect is bone marrow suppression.

【Nature and flavor】 Bitter, warm.
