Moringa oleifera (Moringa) induced acute pancreatitis is an unreported cause of acute pancreatitis. A 48-year-old female who took Moringa for one week complained of abdominal pain, nausea, and vomiting. Her symptoms and biochemical studies showed close accordance with acute pancreatitis. We found no other cause of acute pancreatitis except Moringa. After cessation of Moringa, her symptoms improved and biochemical studies normalized. One month later, she developed recurrent acute pancreatitis after taking Moringa. Thus we thought that Moringa was the cause of acute pancreatitis. No case of acute pancreatitis associated with Moringa has been reported, therefore we report this case.

Here in this study, we investigated the lifespan-extending effect and underlying mechanism of methanolic extract of Moringa olelifa leaves (MML) using Caenorhabditis elegans (C. elegans) model system. To define the longevity properties of MML we conducted lifespan assay and MML showed significant increase in lifespan under normal culture condition. In addition, MML elevated stress tolerance of C. elegans to endure against thermal, oxidative and osmotic stress conditions. Our data also revealed that increased activities of antioxidant enzymes and expressions of stress resistance proteins were attributed to MML-mediated enhanced stress resistance. We further investigated the involvement of MML on the aging-related factors such as growth, food intake, fertility, and motility. Interestingly, MML significantly reduced growth and egg-laying, suggesting these factors were closely linked with MML-mediated longevity. We also observed the movement of aged worms to estimate the effects of MML on the health span. Herein, MML efficiently elevated motility of aged worms, indicating MML may affect health span as well as lifespan. Our genetic analysis using knockout mutants showed that lifespan-extension activity of MML was interconnected with several genes such as skn-1, sir-2.1, daf-2, age-1 and daf-16. Based on these results, we could conclude that MML prolongs the lifespan of worms via activation of SKN-1 and SIR-2.1 and inhibition of insulin/IGF pathway, followed by DAF-16 activation.

OBJECTIVE: To determine bleeding time using Moringa oleifera leaf extract versus saline control in an experimental epistaxis model.
METHODS:
Design: Randomized controlled trial
Setting: Tertiary Government Training Hospital
Participants: Ten adult male New Zealand White rabbits were acclimatized for 1 week in a standard environment. One-centimeter long, full-thickness mucosal wounds in the junction of the nasal floor and anterior part of the septum were treated randomly with topical Moringa oleifera extract or colored isotonic saline control in either right or left nasal cavity, one site at a time. The duration of bleeding - time bleeding started to time bleeding stopped -- was recorded in seconds. Data was subjected to a t-test for paired samples.
RESULTS: The mean bleeding time for wounds treated with Moringa extract was 53 seconds (range 38-70 secs), versus 159 seconds (range 100-218 secs) for controls. The bleeding time in the former was significantly shorter than in the latter (p = .000019, t-stat = 8.139), with a mean difference of 106 seconds between the two groups.
CONCLUSION: Moringa oleifera leaf extract was associated with significantly shorter bleeding time than saline control in this experimental epistaxis model and may be worth investigating further as a hemostatic agent for epistaxis.

Moringa has a long history of edible and medicinal use in foreign countries, this paper collected and sorted out the traditional application of Moringa recorded in the ancient medical books and historical materials of countries and regions along the ancient Silk Road. According to preliminary research, the earliest record of Moringa in China can be traced back to The Bower Manuscript(volume Ⅱ)(about the 4 th-6 th century A.D.) unearthed in Kuqa, Xinjiang. Around the 8 th century, with the communication between countries along the ancient Silk Road becoming prosperous, more and more medical books containing Moringa and its prescriptions were introduced to Tibet, Xinjiang and other places in today's China. The leaves, root bark, seeds and stem bark of Moringa all can be used for medicinal purposes and are recorded in The Ayurvedic Pharmacopoeia of India(API). Among them, Moringa leaves have been approved as a new resource food in China. According to the API, it is of cold property and sweet taste, its post-digestive effect is sweet and has the functions of removing wind, bile and fat, relieving pain, killing abdominal worms, moistening skin, brightening eyes and clearing brain. It can be used to treat edema, parasitic diseases, spleen diseases, abscess, tumor, pharyngeal swelling and other diseases. This study explored and organized the historical evidence of communication through the Silk Road and traditional application records of Moringa, in order to provide the evidence of traditional medicine basis, medicine property and efficacy application reference for the realization of the introduction of Moringa as a new resource of traditional Chinese medicine.

Moringa oleifera Lam (M. oleifera, Moringaceae) is a tree of the Moringaceae family that can reach a height of between 5 and 10 m. The current paper presents cytotoxic effect of M. oleifera fruits and its flavonoids 1 and 2. The viability of HCT116 human colon cancer cells were 38.5% reduced by 150 µg/mL of ethanolic extracts in a concentration-dependent manner; in addition, we observed the apoptotic features of cell shrinkage and decreased cell size. Bcl-2 family proteins were regulated as determined by Western blotting analysis, suggesting that M. oleifera fruits and their flavonoids 1 and 2 induced apoptosis through an intrinsic pathway. Based on our findings, 70% ethanolic extracts of M. oleifera fruits and flavonoids 1 and 2 might be useful as cytotoxic agents in colorectal cancer therapy.
