Everything You Need to Know About Tamanu Oil

Tamanu oil is extracted from the nuts of tropical trees that belong to the Calophyllaceae family. The oil is greenish-yellow and inedible and offers great benefits for your skin. In this post, we will discuss the different ways this oil can improve the health of your skin.

Tamanu Oil – A Summary

If you’ve been inside a health or natural food store, chances are you’ve seen tamanu oil before. Tamanu oil is extracted from seeds that grow on a tropical evergreen tree called the tamanu walnut tree. Tamanu oil and other parts of the tamanu nut tree have been used medicinally for hundreds of years by certain cultures on the Asian, African, and Pacific islands.

Historically, people believed in the skin benefits of tamanu oil. Today, you can find many anecdotal stories about the uses of tamanu oil for the skin. Some studies suggest that tamanu oil may prevent tumor growth in cancer patients, treat vaginitis, and help reduce symptoms in people with HIV. Reliable Source Tamanu oil is generally not incorporated into Western medicine.

Oil originates from Polynesia, where traditionally it is also quite important. Oil was used as fuel decades ago. It was widely used to generate electricity to provide power to radios during World War II.

Today, tamanu oil is widely used in Polynesia and Southeast Asia to treat various skin problems. In parts of southern India, the oil is used particularly to treat skin conditions and some forms of rheumatism, according to anecdotal evidence.

But the greatest use of tamanu oil, as we discussed, is in the treatment of a variety of skin and hair problems. We will discuss all of those now.

How can Tamanu oil benefit you?

Tamanu oil is believed to have a number of health and beauty benefits, from wound healing to healthier hair. While not all the claims you come across have been scientifically researched, many are.

1. Helps fight acne

Tamanu oil has anti-inflammatory and antibiotic properties, which work to alleviate skin problems like acne. These properties make the oil an essential ingredient in the protective and regenerative formulations of the skin.

2. Can treat hyperpigmentation

One of the most common causes of hyperpigmentation is skin inflammation that occurs due to excessive exposure to UV rays. Since the oil has anti-inflammatory properties, it can help treat hyperpigmentation.

3. It helps to treat eczema

The anti-inflammatory properties of tamanu oil can also help treat eczema. Studies show that the decoction of tamanu leaves can be used to relieve dermatosis and eczema.

4. It can help the treatment of psoriasis

Psoriasis is an inflammatory skin condition. Tamanu oil contains calophyllolide, a compound that showed curative and anti-inflammatory effects in a mouse study. Another study showed that tamanu leaf extracts reduced inflammation of cells in the laboratory.

5. Treat dry skin

Tamanu oil is believed to penetrate all three layers of the skin, moistening it at a much deeper level. It also helps heal cracks and sores on the skin.

6. Calm the rashes

The anti-inflammatory properties of the oil are at stake here. Gently applying the oil to the rashes can help heal them. The moisturizing properties of the oil promote greater healing. These are some of the main benefits of tamanu oil. Although some of these are supported by research, some are anecdotal claims that are being investigated further. Tamanu oil is also believed to offer the following benefits. We suggest that you check with your doctor before using the oil for the benefits mentioned below.

7. Can delay wrinkles

This has to do with the fatty acids in the oil, which lubricate and nourish your skin. The oil promotes the elasticity and firmness of the skin, thus delaying the appearance of wrinkles.

8. Can help reduce stretch marks

There is very little reliable evidence of this. Anti-inflammatory properties can lighten stretch marks and associated scars. It is also believed to have cell renewal properties that help attenuate stretch marks.

9. Can treat toenail fungus

Some anecdotal evidence indicates that the nail fungus responds quite well to tamanu oil. You can apply a few drops of oil to the affected area. Repeat two or three times a day for about a week.

10. Could strengthen hair

The regenerative properties of tamanu oil can also work well on the scalp, possibly strengthening the roots of the hair. The oil can add moisture to the hair, preventing a dry scalp. This can stop hair loss and, as a result, stimulate hair growth. Like any other oil, tamanu oil has its ways of improving the health of your skin. But then, it may not be suitable for everyone. You should be aware of the following side effects.

Any side effects of tamanu oil?

The oil is generally considered safe, but it can cause allergies like itching, redness, and irritation in some people. So do a patch test – if you don’t experience reactions the oil should be right for you.

Please note that tamanu oil is considered a health supplement and is therefore not regulated by the United States Food and Drug Administration (FDA) as capable of treating or curing any disease. In fact, the FDA has filed lawsuits against companies in Utah and Oregon that made claims about the skin benefits of tamanu oil.

If you have an allergy to nuts, you should avoid tamanu oil. As the oil is extracted from the nuts of trees that belong to the Calophyllaceae family, people with nut allergies may experience adverse reactions.

Alternatives to tamanu oil

Tamanu is a walnut oil and not an essential oil, but the following essential oils are alternatives to tamanu oil. Which one you choose depends on the effect you are looking for. Be sure to use as directed, as some of these essential oils must be diluted with a carrier oil before being applied to the skin to avoid irritation.

Here are three alternatives and what they can do.

  • Tea tree oil : Tea tree oil has been extensively researched. It has anti-inflammatory and antibacterial properties that make it effective in treating minor wounds, itching, and skin conditions such as eczema and acne.
