Avocado Leaf Extract
Also known as: Avocado leaf extract, Avocado leaf, *Persea americana* Mill.
Overview
Avocado leaf extract is derived from the leaves of the avocado tree (*Persea americana* Mill.), noted for its traditional medicinal properties. The extract is utilized primarily for its antihypertensive, antioxidant, and potential anti-inflammatory effects. Key bioactive compounds found in this extract include quercetin, phenolic acids, and various minerals, which contribute to its therapeutic potential. However, research on avocado leaf extract is still emerging, primarily consisting of small-scale animal studies and a limited number of human trials. Large-scale randomized controlled trials (RCTs) and systematic reviews are needed to better establish the effectiveness and safety of this herbal supplement across diverse populations.
Benefits
The most documented benefit of avocado leaf extract is its antihypertensive effect, evidenced by studies that demonstrate significant reductions in systolic and diastolic blood pressure in animal models, particularly hypertensive rats. For instance, one study noted a decrease in systolic blood pressure from 175.00±21.57 mmHg to 106.25±9.21 mmHg in treated rats. While antioxidant and anti-inflammatory properties have been suggested, these benefits are less substantiated in human studies. Ultimately, the current evidence highlights a promising effect in hypertensive conditions, although larger, more robust human trials are required to confirm these findings and establish effectiveness in broader populations.
How it works
The antihypertensive effect of avocado leaf extract is primarily believed to be mediated through the inhibition of the angiotensin-converting enzyme (ACE), which plays a critical role in regulating blood pressure. By inhibiting ACE, the extract may facilitate vasodilation and reduce blood pressure levels. Furthermore, while the focus has been primarily on ACE, other biological pathways may also influence its effects. There is limited data regarding the absorption and bioavailability of the extract in humans.
Side effects
Overall, avocado leaf extract is considered to have a favorable safety profile based on animal studies; however, human safety data remains scarce. Common and uncommon side effects are not well-documented due to the limited scale of human trials. Potential risks include interaction with antihypertensive medications, given its ACE-inhibiting properties, warranting caution for individuals on such treatments. There are no established contraindications, but it is advisable for pregnant or breastfeeding women to consult healthcare professionals prior to use, given the insufficient safety data available.
Dosage
The minimum effective dose for humans has yet to be established. In animal studies, doses around 100 mg/kg were utilized to observe antihypertensive effects. There is currently no optimal or maximum dosage range determined for humans, nor has a specific timing for administration been highlighted. Most usage is in extract forms, including nanoparticle formulations, but absorption factors remain unclear. As such, individuals should exercise caution and consider professional guidance before initiating supplementation.
FAQs
