Kevin asked in English on September 15, 2022: "Hello Professor Lin, I want to know if you can provide some insights on the impact of Maka root supplements on men and women. The Maka supplements sold on Amazon have received good user reviews, but I am not sure if there is any research to support it. Thank you for your time."Tom Asked on 2022-9-22: "Hello Professor, thank you very much for sharing and answering many relevant medical health care knowledge during your retirement. Taiwan's nursing products called Maka have begun to be red in the past two or three years. It claims that it has the effect from enhancing physical strength to helping sleep and even suffocating the sun. I wonder if the professor has any relevant opinions or opinions on it? Thank you again."
{9 99}is fine, whether it is Chinese or English, Maka's flattery is very unsatisfactory, especially in terms of sexual ability and reproductive ability. But the question is, is this kind of flattery reasonable? I have asked you to read the relevant clinical research papers in the past 20 years (2003-2022) yesterday (How much scientific research papers are there in Maka’s praise?) Now I would like to read the related summary articles from these 13 years (2010-2022), and especially pay attention to the article in 2018.
2010: Maca (L. meyenii) for improving sexual function: a systematic review. Conclusion: "The results of our system evaluation provide limited evidence for the effectiveness of maca's improvement of sexual function. However, the total number of trials, total sample volume and average methodological quality of the main studies are too limited to come to an accurate conclusion. It is necessary to conduct more stringent research."
2010: Medicinal plants as alternative treatments for female sexual dysfunction: utopian vision or possible treatment in climate women? (Pharmative plants as an alternative method for female sexual dysfunction: Utopian vision or possible method for women in menopause?). Conclusion: "We highlight most plants that are usually related to the female reproductive system, including: at the age, total cohosh, flower, apricot, cherry, maca, terrestrial terrestrial symptoms, red leaf axe and maria. However, at present, this review cannot recommend plants with sufficient certification levels to treat female sexual dysfunction."
2011: Maca (Lepidium meyenii) for treatment of menopausal symptoms: A systemic review (Maca is used to treat menopause symptoms: systematic review). Conclusion: "Our system evaluation results provide limited evidence for the effectiveness of Maka in treating menopause symptoms. However, the total number of trials, total sample volume, and average methodological quality of the main studies are too limited to come up with an accurate conclusion. In addition, safety has not been proven. Therefore, effectiveness and safety should be tested in larger-scale studies."
2014: Sexual enhancement products for sale online: raising awareness of the psychological effects of yohimbine, maca, horny goat weed, and Ginkgo biloba (sex enhancement products sold online: to enhance people's understanding of the mental effects of yohembe, maca, epimedium and silver leaf). Conclusion: "The most common sexual enhancement products on the Internet include Yohembe, Maca, Epimedium and Silver Apricot. According to reports, these four substances are accompanied by the occurrence of adverse events and the development of psychological symptoms such as emotional changes, anxiety and hallucinations, and behaviors. The uncontrolled supply of sexually enhanced products containing potentially harmful substances is an important public health problem. The possible impact on population health, especially among subjects with mental illnesses, is often at risk of sexual dysfunction, which may be significant. This new trend requires extensive research and monitoring. ”
2016: The use of maca (Lepidium meyenii) to improve semen quality: A systematic review (Use maca to increase semen quality: systematic review). Conclusion: "The results of our system ratings provide a suggestive evidence for the effectiveness of Maca in improving semen quality. However, the total number of trials, total cost volumes, and bias risk barriers to the inclusion study lead to a reliable conclusion. It is necessary to conduct a more stringent study."
2018: Is the hyper around the reproductive health claims of maca (Lepidium meyenii Walp.) justified? (Is the flattery of reproductive health claims that surround Maca's reproductive health claims?). Author Michael Heinrich is Director and Professor of the Centre for Physicians and Botanical Age at the University of London.
Discussion: Over the past two decades, Maka has been introduced to the global market and has been touted as a "Perruto" that can improve sexual desire and fertility. With its promotion on the Internet, demand for Maka has increased rapidly. It can also cure menopausal symptoms, erectile dysfunction and benign prostate hyperplasia. The surge in demand for this plant has changed from traditional planting methods to large-scale production using fertilizers and slaughter agents; because Maca is now planted outside the Andes, such as Yunnan, China. This may affect the chemistry and composition of the plant, and thus the quality, safety and efficacy of Maca products. At the same time, with the popularity of maca, research on the properties of maca's medicines has mainly focused on the aphrodisiac and fertility enhancement characteristics of maca. So far, no conclusive results have been achieved intra-organized studies and clinical trials. Some key limitations are method and sample size. Chemical analysis has led to the discovery of new compounds unique to Maca, such as “macamides” and other active promoters such as glucosinolates; the drug use of Maca has been made due to its lack of data.
Conclusion: So far, from a scientific perspective, Maka's health initiatives cannot be fully supported and more research is needed. Originally knowledge about the health benefits of Maka has been delineated to meet the demand of the growing herbal medicine market. This globalization (or hype, especially in China) has also had serious consequences for local producers in Peru. During this rapid expansion period, the lack of protocols for standardized maca production and marketing threatens consumer safety and sustainability.
2021: Lepidium meyenii (Maca) in male reproduction. Conclusion: "This study shows results related to the effects of maca on semen quality and quantity, sexual behavior and male reproductive tract diseases. Although extensive research has been conducted on different animal species, further research is still needed to understand the mechanism of maca's action."
Additional information:
The US FDA issued Peru Maca containing hidden drug ingredients on June 26, 2019: The US Food and Drug Administration recommends that consumers do not buy or use Peru Maca. The product was discovered when checking international mail. FDA laboratory analysis proves that Perumaca contains sildenafil, an active ingredient in the FDA-approved drug Viagra used to treat erectile dysfunction. This undeclared ingredient may interact with salt nitrate in certain prescription drugs such as nitroglycerin and may reduce blood pressure to dangerous levels. People with diabetes, high blood pressure, high calcification, or heart disease are often taken by salt nitrate.
