Moringa is a tree belonging to the genus Moringa in the family Moringaceae. Its bark is soft and woody, with prominent lenticels and leaf scars on its branches, and short, soft hairs on its twigs. The leaves are usually pinnately compound, with linear or club-shaped, slightly curved glands at the base of the pinnae. The inflorescences are widespread; the capsules are slender, with ribs on each valve; the seeds are nearly spherical. It flowers year-round and fruits from June to December.
Moringa, rich in polyphenols, vitamins, minerals, and dietary fiber, has traditionally been considered beneficial for controlling blood sugar, regulating blood lipids, and blood pressure. However, a systematic review and meta-analysis published in the journal Nutrients, which comprehensively evaluated previous randomized controlled trials, yielded unexpected results. This study strictly followed the PRISMA 2020 guidelines and was prospectively registered on the PROSPERO platform, ultimately including nine RCTs covering 649 participants. The study found that moringa supplementation did not show significant improvements in most cardiovascular metabolic parameters, including weight, BMI, waist circumference, and key lipid indicators such as triglycerides, total cholesterol, LDL cholesterol, and HDL cholesterol. These results suggest that the benefits of moringa for cardiovascular metabolic health may not be as significant as traditionally believed. The study employed a standardized mean difference random-effects model pooled analysis, used the Cochrane RoB 2 tool to assess risk of bias, and used the GRADE system to grade the quality of evidence, ensuring the scientific rigor and transparency of the analysis process.
Moringa extract comes from the Moringa tree, a fast-growing tree native to the Indian subcontinent, often called the "miracle tree." Depending on the part used (mainly leaves and seeds), its extract is rich in nutrients and possesses various bioactivities.
| Extraction site | Main active ingredients/uses | Remark |
| leaf | Super Nutrition Powerhouse: Rich in vitamins (A, C, E), minerals (calcium, potassium, iron), protein, and antioxidants (flavonoids, polyphenols). | Nutritional support is often provided by superfoods or dietary supplements. |
| seed | Highly efficient purification: Rich in positively charged polypeptides and proteins, which can neutralize negatively charged impurities in water. | Water purification: Studies have shown that its powder can effectively remove most impurities and bacteria from water, making it a natural flocculant. |
| High-quality oils: contain clear, sweet-tasting, and antioxidant-rich oils. | Moringa seed oil (Beian oil): Used in cosmetics (moisturizing, skin care) and as a high-grade edible oil. | |
| Roots/Bark | Alkaloids (moringa) etc. | Traditional medicinal use: Used in medicine to treat various diseases. Caution: The roots may contain toxic alkaloids; extreme caution is advised when consuming them. Commercial extracts typically have these components removed. |
Main Efficacy and Applications
Due to its rich components, Moringa extract has wide applications in multiple fields:
1.Nutritional Supplements and Health Foods
Comprehensive Nutritional Supplementation: Moringa leaf powder is extremely high in protein, vitamins, and minerals, making it a high-quality natural nutritional supplement, especially suitable for malnourished areas or vegetarians.
Powerful Antioxidant Effects: Its various antioxidants (such as quercetin and kaempferol) help combat oxidative stress, delay aging, and enhance immunity.
Anti-inflammatory Potential: Studies have shown that Moringa extract may help alleviate inflammatory diseases such as arthritis by inhibiting inflammatory factors.
Assisted Regulation of Blood Sugar and Lipids: Some animal and human studies have shown that Moringa leaf extract helps lower blood sugar, cholesterol, and triglyceride levels.
2.Water Purification
Moringa seed powder, as a natural, biodegradable, and low-cost flocculant, is used in the initial purification of drinking water in developing countries, effectively settling sediment, bacteria, and other contaminants.
3.Cosmetics and Personal Care
Moringa Seed Oil: Rich in oleic acid, easily absorbed, and with excellent moisturizing and nourishing effects, it is commonly used in face creams, shampoos, and conditioners to help repair the skin barrier and nourish hair.
Antioxidant and Anti-aging: Moringa leaf extract, due to its high antioxidant properties, is added to skincare products to help protect the skin from free radical damage.
4.Other Applications
Animal Feed: Moringa leaf powder, as a feed additive, can improve animal growth performance and immunity.
Biofuels: Moringa seed oil can be used to produce biodiesel.
