The impotence is mainly from the male physiological aspect to increase the male virility. In today's society, having a good sex life has become a part of a healthy life. Compared with chemical drugs, medicinal plants are characterized by high safety and little toxic and side effects, so the study of medicinal plants in the field of impotence is one of the hot spots of medical and pharmaceutical research. This paper reviews the research progress of some medicinal plants with impotence. But, the author suggests do not know the plant to eat in disorder, should ask a doctor first.
Maca (Lepidium meyenii Walp.) belongs to the solitary herb of cruciferae family. Its main medicinal parts are underground rhizomes. Zheng BL et al.  found that maca liposoluble extract can significantly enhance the libido and sexual ability of mice, increase the number of planks and mating in male mice, and improve the erectile function of erectile dysfunction rats. At the same time, the erectile latency period of the testicular rats can be shortened, which indicates that maca has a significant effect on improving sexual function. Yu longjiang et al.  compared the effects of water extract, petroleum ether extract and ethanol extract of maca powder on the sexual vitality of male mice. The results showed that each extract of maca significantly shortened the incubation period of male mice and increased the number of mating. Petroleum ether extract is the most effective. According to the author, as a popular health product in China, the famous "healthy" maca tablet is mainly because of its high content of maca powder, which is much more convenient than buying messy maca in the market.

Five Chinese wolfberry
Medlar (Lycium chinense Mill.) plants of the genus belongs to the solanaceae medlar, medicinal part with medlar, dry mature fruit, Chinese wolfberry leaves (tender stem leaf) to bone and skin (dry skin), mainly containing unsaturated fatty acids, crude fiber, alkaloids, amino acids and trace elements, such as active ingredients are mainly Chinese wolfberry polysaccharides, wolfberry seed oil and betaine. Lycium barbarum polysaccharides is one of the main components of lycium barbarum, and the content of polysaccharides in dried fruits of lycium barbarum amounts to 2.70%~4.90%. Lycium barbarum polysaccharides can obviously shorten the penile erection latent period, ride the latent period, and increase the percentage of the animal ride. Increase the serum T level and decrease the level of E2. Increase the organ coefficient, sperm count and vitality of the accessory gland. The mechanism of lycium barbarum to enhance the sexual function of semi-castrated rats is not as a male hormone substitute, but may play a role by regulating the function of hypothalamic-pituitary-gonad axis .
Allium tuberosum Rottler. Studies in recent years have shown that the contents of Fe, Mn and Zn in traditional Chinese medicine of kidney-tonifying and yang-aiding are higher. Leeks are rich in Fe, Mn, Zn and VE, and VE can increase men's sperm count and enhance sperm vitality, and also stimulate gonads to secrete hormones. Therefore, leeks can warm the kidney and help the Yang . Leek extract can significantly increase the content of testosterone and NO, and increase the concentration of NO, and enhance the ability to stimulate penile erection. Increased testosterone concentration promotes the production of nitric oxide synthase (NOs) and arginine enzyme, inhibits the production of phosphodiesterase 5 (PDE5) and improves sexual function .

Natural medicines have been used for thousands of years in China, among which plants account for the majority. In recent years, with the deepening of the research on medicinal plant chemical ingredients and their biological activities, the therapeutic effect and curative effect have been more and more concerned and recognized by the world, which also brings hope to the treatment and even cure of many diseases. At present, the research on the medicinal plants of zhuang Yang is not very comprehensive. Most of the research work is mainly on the extract of a part or the whole plant, but the problems of which components play the role of zhuang Yang, whether a single component plays a role or a combination of ingredients to produce curative effect are still to be solved. Therefore, it has a broad prospect to study the natural medicine which has the function of aphrodisiac.
