This oil is typically either cold pressed or refined and is known as one of the expensive natural oils on the market. Walnut oil has grown in popularity around the world and is cultivated in many countries including the United States.

Benefits & Uses of Walnut Oil
Walnut oil is able to help you with psoriasis, eczema, sunburn, premature aging, a weak immune system, obesity, hair loss, dandruff, wrinkles, high blood pressure, stress, anxiety, and diabetes, as well as high risk of heart disease.
There are three critical parts of walnut oil that help protect the skin – the antibacterial, antioxidant, and anti-inflammatory elements of this oil. The antioxidants are able to reduce the appearance of lines and wrinkles in the skin, helping to keep you looking younger. The antibacterial components can help protect against skin pathogens, which are constantly bombarding the largest and most exposed organ in the body. Finally, the anti-inflammatory nature of the oil helps soothe chronic conditions like eczema and psoriasis, as well as acute cases of inflammation or allergic reaction.
Improves Heart Health
Walnut oil is composed of more than 70% polyunsaturated fats, as well as a significant amount of monounsaturated fats. This no-cholesterol oil is excellent for improving heart health by increasing circulation, decreasing fat deposition, boosting energy and lowering blood pressure. Together, these effects will mean a lowered risk of atherosclerosis, heart attack, and stroke.
By massaging this oil into your scalp, often in conjunction with other essential oils, as walnut oil is a great carrier oil, you can moisturize the skin and eliminate various infections. This can also help you eliminate any signs of dandruff, and prevent those unsightly flakes on your shoulders.
The anti-inflammatory powers of this oil work both inside and out. If you topically apply walnut oil to sore joints and muscles, it can help reduce inflammation and pain, but when consumed, this oil will also improve blood vessels function, aiding heart health even further.
Has Antioxidant Effects
Free radicals that are constantly produced through cellular metabolism affect the body’s cells and tissues in various ways, namely increasing the risk of cancer and other diseases. High levels of antioxidants found in walnut oil help reduce the oxidative stress throughout your body.
Prevents Hair Loss
There is a significant amount of potassium found in walnut oil, which has been proven to boost hair growth and stimulate the production of new cells and protects follicle health. The moisturizing and antibacterial effects of this oil can also help prevent premature loss of hair.
People who struggle to maintain their blood glucose can find some help in walnut oil, as it can aid to regulate blood sugar levels and insulin production in the pancreas. This can help people with diabetes lead a normal life and decrease their risk of developing it. According to a 2016 study in the International Journal of Endocrinology Metabolism, daily intake of walnut oil (15g for three months) showed improvement in the blood glucose levels of subjects with type-2 diabetes.
Boosts Immune System
Your immune health starts on the skin, but it ends inside the respiratory and gastrointestinal tracts. The significant boost of antioxidant and antibacterial properties in walnut oil can improve organ system function and relieve strain on the immune system so it can focus on more pressing threats.
The aroma of walnut oil is often enough to calm the mind and soothe the senses, but consuming some of this oil is also known to relieve stress. By providing an energetic boost to the body and mind, this oil has been associated with balancing mood and reducing symptoms of anxiety and depression.
Side Effects of Walnut Oil
The side effects of using walnut oil are extremely limited, consisting only of potential stomach issues, and a few cardiovascular concerns. For the majority of people, use of this oil is perfectly safe, when applied or consumed in moderation, and after speaking with your doctor about any potential risks, given your individual conditions.
It is possible that the blood pressure-lowering effects of this oil can cause complications with other hypertension medications, so it is best to speak with your doctor before using this oil internally.
Similarly, walnut oil can be great for diabetic patients or people at high risk of diabetes but it can also cause dangerously low levels of blood sugar, if used in conjunction with certain drugs. Diabetics should use this oil in their meals with caution.
As is true with many powerful, concentrated oil, walnut oil may cause skin irritation when used topically for cosmetic or medicinal purposes. Apply a small amount to a patch of skin and wait a few hours to see whether there is a negative reaction, particularly if you have sensitive skin.
Although the internal use of walnut oil is perfectly safe, it is extremely potent and can cause an inflammatory response in your gut. This could take the form of stomach upset, cramping, bloating, nausea, diarrhea or even vomiting. If this occurs when you consume walnut oil, stick with the topical applications.
