7 Potential Health Benefits of Walnut Leaves

Health Benefits of Walnut Leaves

Walnut leaves ((Tetracarpidium conophorum Mull. Arg), like many other plant leaves, have been used in traditional medicine for their potential health benefits. In this article, you will find out the health benefits of walnut leaves, how to use it and the potential side effects.

Walnut leaves are compound leaves, meaning they are made up of multiple smaller leaflets. The number of leaflets can range from 5 to 23, depending on the species of the tree. The leaves are typically pinnate, which means they have a feather-like shape. The leaflets are short-stalked and lanceolate in shape, meaning they are long and narrow with pointed tips. The leaves are green in color and have a slightly glossy appearance.

Walnut leaves have known to contain essential properties that help to keep the body safe and healthy.

Now, let’s take a look at the health benefits of walnut leaves, how you can use them, and the risk associated with eating walnut leaves.

7 Health Benefits of Walnut Leaves

Here are some potential health benefits associated with walnut leaves:

1. Antioxidant properties

Walnut leaves contain various bioactive compounds, including phenolic compounds and flavonoids, with antioxidant properties. Antioxidants help neutralize harmful free radicals in the body, reducing oxidative stress and potential cell damage.

Another 2007 study on walnut leaves demonstrated that they contain phenolic compounds which might be responsible for it’s antioxidant activities.

2. Anti-inflammatory effects

Some studies suggest that walnut leaves may possess anti-inflammatory properties. Inflammation is associated with various chronic diseases, such as heart disease, diabetes, and certain types of cancer. The anti-inflammatory potential of walnut leaves may help mitigate inflammation-related health issues.

Furthermore, a 2022 review on medicinal uses, nutritional value, and anti-Inflammatory effects of walnut leaves proved that the leaves contained flavonoids and bioactive compounds that gave it it’s anti-Inflammatory potential.

3. Antimicrobial activities 

Walnut leaves have been investigated for their potential antimicrobial properties. Some studies have shown that extracts from walnut leaves exhibit activity against certain bacteria and fungi. This suggests that they may possess antimicrobial properties that could be beneficial for preventing or treating certain infections.

A study conducted in 2013 investigated the potentials of walnut (Tetracarpidium conophorum Mull. Arg) leaf extracts as antimicrobial agents for fish diseases.

According to the findings, the tested organisms showed antibacterial activity in response to extracts from walnut leaves and onion bulbs, demonstrating their potential use in treating fish diseases.

4. Antinociceptive effects

Antinociceptive refers to the process of reducing or blocking the perception of pain by the nervous system in response to a potentially harmful or noxious stimulus.

In a 2012 study, walnut leaves were found to exhibit antinociceptive effects through non-opioid receptors, as well as anti-inflammatory effects against acute and chronic inflammation. As a result, they show promise as potential analgesic and anti-inflammatory agents for the treatment of conditions like rheumatoid arthritis.

5. Potential antidiabetic properties

Walnut leaves have been traditionally used in teas and decoctions to treat diabetic symptoms.

In vivo studies have confirmed the ability of walnut leaves to improve hyperglycemia in humans, but the specific compounds responsible for this effect were unknown.

A 2016 study isolated and identified two compounds from the walnut leaf extract that belong to the megastigmane class and have significant antidiabetic activity.

The study also evaluated the compounds’ potential to affect glucose uptake in cell lines. The findings could lead to a more informed use of walnut leaf-based beverages in the treatment of diabetes.

6. Promotes skin health

Topical application of walnut leaf extract or preparations has been used traditionally for skin health. It is believed to possess astringent properties to help tone and tighten the skin. Additionally, walnut leaves’ antioxidant and anti-inflammatory properties may contribute to maintaining healthy skin.
