Introduction to Avocado Leaves
Avocados are hugely popular fruits known for their rich, creamy texture and multitude of health benefits. However, most people tend to overlook the nutritional value of avocado leaves. For centuries, these vibrant green leaves have been used in traditional medicine to treat various ailments.
Avocado leaves contain bioactive compounds like estragole, anethole, cinnamyl acetate, and polyphenols which possess antimicrobial, anti-inflammatory, analgesic, antidiabetic, and antioxidant properties (Bopda et al., 2014).
This article will discuss the various health benefits of avocado leaves supported by scientific research.
Nutritional Value
Avocado leaves are highly nutritious and pack a healthy dose of antioxidants, polyphenols, flavonoids, terpenoids, and essential oils (Pahua-Ramos et al., 2018).
100 grams of avocado leaves contain (Bopda et al., 2014):
- Water - 50-60g
- Protein - 11.8g
- Fiber - 15.9g
- Fat - 5.5g
- Carbohydrates - 38.7g
- Calcium - 961mg
- Phosphorus - 113mg
- Iron - 9.9mg
- -carotene - 19.40mg
- Vitamin C - 8.33mg
Antioxidant Properties
Avocado leaves are a powerhouse of antioxidants. The polyphenols, flavonoids, vitamin C, and -carotene can neutralize free radicals and protect against oxidative damage (Pahua-Ramos et al., 2016).
The antioxidants in avocado leaves exhibit anti-inflammatory, anti-aging, anticancer, and immune-enhancing effects in the body (Bopda et al., 2014).
Anti-Inflammatory Effects
Inflammation is the root cause of most chronic diseases. The flavonoids and polyphenols in avocado leaves can inhibit inflammatory markers like TNF-, IL-6, IL-1, nitric oxide synthase, and cyclooxygenase-2 (Pahua-Ramos et al., 2018).
Animal studies reveal the anti-arthritic and analgesic properties of avocado leaves. The anti-inflammatory effects can help relieve joint pain, swelling, and stiffness in arthritis (Ozolua et al., 2016).
Health Benefits
Supports Liver Health
Avocado leaves can boost liver health in several ways. The antioxidant phytochemicals protect liver cells from toxic damage caused by free radicals. They enhance liver detoxification and prevent fat accumulation in the liver (Ozolua et al., 2016).
Research shows that avocado leaf extracts can revitalize and rejuvenate liver function in liver-damaged animals by facilitating rapid regeneration of liver cells (Ojewole et al., 2008).
Regulates Blood Sugar
Avocado leaves display antidiabetic effects by enhancing insulin sensitivity, stimulating insulin secretion from the pancreas, inhibiting glucose absorption in the gut, and modulating genes involved in carbohydrate metabolism (Navekar, 2020).
Animal studies reveal that avocado leaf extracts can lower blood sugar in diabetic rodent models by 20-60% (Ojewole et al., 2007).
Promotes Heart Health
Avocado leaves can support cardiovascular function in many ways. The antioxidant and anti-inflammatory effects protect blood vessel lining and prevent atherosclerotic plaque buildup. They also relax blood vessels, lower triglycerides and cholesterol levels in the blood, and prevent platelet aggregation (Bopda et al., 2014; Pahua-Ramos et al., 2018).
These beneficial vascular effects help reduce high blood pressure and the risk of heart attacks and strokes.
Aids in Weight Loss
The high fiber content and antioxidant properties of avocado leaves can promote weight loss. Fiber enhances satiety and reduces calorie intake. Antioxidants, on the other hand, boost metabolism and increase fat burning (Sulaiman et al., 2018).
Animal studies reveal that avocado leaf extracts may inhibit weight gain by modulating gene expression involved in adipogenesis or fat cell production (Na et al., 2011).
Has Antimicrobial Properties
Avocado leaves have traditionally been used to treat bacterial, fungal, and parasitic infections. Research shows that bioactive compounds like estragole, anethole, and cinnamyl acetate give avocado leaves broad antimicrobial effects (Bopda et al., 2014).
Avocado leaf extracts have been found effective against drug-resistant microbes like Staphylococcus aureus, Escherichia coli, Candida strains, etc. They may also treat malaria by eliminating Plasmodium parasites from red blood cells (Lemmens-Gruber et al., 2006).
How To Use Avocado Leaves
Avocado Leaf Tea
The most popular way to use avocado leaves is to brew them into a medicinal tea. To make avocado leaf tea:
- Rinse 4-5 avocado leaves properly under running water.
- Cut the leaves into small pieces and crush them lightly using a mortar and pestle.
- Boil the crushed leaves in 2 cups water for 5 minutes.
- Let it steep for another 5-10 minutes.
- Strain and drink the tea warm.
Drink 1-2 cups avocado leaf tea daily to enjoy its antioxidant, anti-inflammatory, and other medicinal effects.
Apply Topically
Create a poultice by mashing avocado leaves into a paste and apply it topically to relieve inflammatory conditions like arthritis, skin ulcers, abscesses, etc. You can also use avocado leaf juice or decoction for a topical wash (Ozolua et al., 2016).
Take Supplements
Avocado leaf capsules, tinctures, extracts, and powder supplements are also available. Make sure to consult an herbalist on the appropriate dosage according to your health status.
Due to lack of safety studies, supplements should be avoided during pregnancy and breastfeeding.
Side Effects and Precautions
Avocado leaves are likely safe for most people when consumed in moderation as food or medicine. However, those sensitive to birch pollen might experience oral allergy syndrome symptoms after ingesting avocado leaf tea or extracts.
Due to the blood sugar lowering effects, diabetic patients on medications should exercise caution and monitor glucose levels closely to avoid hypoglycemia.
Very high doses may be toxic to the liver and lead to liver enlargement and lesions (Ojewole et al., 2008). So it's best to stick to culinary amounts when using avocado leaves.
Further studies are warranted on the long term safety of avocado leaves during pregnancy and breastfeeding.
Conclusion
In many parts of the world, avocado leaves have been used in cooking and as natural medicine for generations. Modern research is now uncovering the science behind the health claims.
Avocado leaves are loaded with bioactive antioxidant, anti-inflammatory, and antimicrobial compounds. They can help manage blood sugar, promote liver and heart health, aid weight loss, and relieve pain and inflammation.
