Melia Azadirachta Leaf Extract
Also known as: Melia azedarach, Persian lilac, Chinaberry, White cedar
Overview
Melia azedarach, commonly known as Persian lilac, Chinaberry, or White cedar, is a deciduous tree native to Asia and Australia. Its leaves have been traditionally used in medicine for their purported antimicrobial, antiviral, and anticancer properties. The leaves are rich in phenolic and flavonoid compounds, which are believed to contribute to its therapeutic effects. While traditional medicine has long recognized its potential, scientific research is still in its early stages, primarily consisting of in vitro and in vivo experiments. The quality of available evidence is limited due to the lack of human clinical trials, particularly randomized controlled trials (RCTs), making it difficult to ascertain its true efficacy and safety in humans. Further research is needed to validate these preliminary findings and establish its role in modern medicine.
Benefits
Melia azedarach exhibits antibacterial activity against both Gram-negative and Gram-positive bacteria, as demonstrated in in vitro studies. It also shows potential antiviral effects against viruses like SARS-CoV-2, with in vitro studies indicating robust activity. Additionally, some research suggests anticancer and antimalarial properties, although these findings require further investigation. However, it's important to note that these benefits are primarily based on preclinical studies, and there is a lack of human clinical trials to confirm these effects in humans. Therefore, the clinical significance and effect sizes are not yet quantified, and the time course of benefits remains undefined. More research is needed to determine the specific populations that may benefit most from Melia azedarach.
How it works
The mechanism of action of Melia azedarach primarily involves interaction with bacterial cell walls and membranes, potentially disrupting their integrity and leading to cell death. In antiviral activity, it may inhibit viral replication through various pathways. The extract's interaction with body systems may also affect the immune response and cellular health, although the specific molecular targets are not yet well-defined. Absorption and bioavailability in humans have not been studied, making it difficult to determine how effectively the active compounds are utilized by the body.
Side effects
While Melia azedarach is generally considered safe based on traditional use, comprehensive safety data is lacking. Common side effects are not well-documented, but potential gastrointestinal issues have been reported as uncommon side effects. Rare side effects are not reported in the available literature. Drug interactions are currently unknown, and contraindications include pregnancy and breastfeeding due to the lack of safety data in these populations. Caution is advised for children and individuals with compromised health. More research is needed to fully understand the safety profile of Melia azedarach and to identify any potential adverse effects or drug interactions.
Dosage
Due to the limited research on Melia azedarach, the minimum effective dose, optimal dosage ranges, and maximum safe dose have not been established. Timing considerations for administration are also not specified. It is typically used as a leaf extract, but absorption factors are unknown. There are no identified required cofactors for its activity. Given the lack of human studies, it is crucial to consult a healthcare provider before using Melia azedarach, and caution should be exercised until more data on its safety and efficacy become available.
FAQs
