Peanut Oil

What is it?

Peanut oil is the oil from the seed, also called the nut, of the peanut plant. Peanut oil is used in cooking and is also used to make medicine.

Peanut oil is used for high levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia), heart disease, joint pain, dry skin, and other conditions, but there is no good scientific evidence to support these uses.

How effective is it?

Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, Ineffective, and Insufficient Evidence to Rate.

The effectiveness ratings for PEANUT OIL are as follows:

Insufficient evidence to rate effectiveness for...

  • Constipation.
  • Dry skin.
  • Heart disease.
  • High levels of cholesterol or other fats (lipids) in the blood (hyperlipidemia).
  • Joint pain.
  • Other conditions.
More evidence is needed to rate the effectiveness of peanut oil for these uses.

How does it work?

Peanut oil is high in monounsaturated "good" fat and low in saturated "bad" fat, which is believed to help prevent heart disease and lower cholesterol. Most studies in animals suggest that peanut oil might help to reduce fatty build up in blood vessels. However, not all studies agree.

Are there safety concerns?

When taken by mouth: Peanut oil is LIKELY SAFE for most people when consumed as a food or taken as a medicine. Peanut oil can cause allergic reactions in people who have an allergy to peanut.

When applied to the skin: Peanut oil is LIKELY SAFE when applied to the skin.

When given as an enema (rectally): There isn't enough reliable information to know if peanut oil is safe to use or what the side effects might be.

Special precautions & warnings:

Pregnancy and breast-feeding: There isn't enough reliable information to know if peanut oil is safe to use in amounts greater than those found in food when pregnant or breast-feeding. Stay on the safe side and stick to normal food amounts.

Allergy to peanuts, soybeans, and related plants: Peanut oil can cause serious allergic reactions in people who are allergic to peanuts, soybeans, and other members of the Fabaceae plant family.

Are there interactions with medications?

It is not known if this product interacts with any medicines.

Before taking this product, talk with your health professional if you take any medications.

Are there interactions with herbs and supplements?

There are no known interactions with herbs and supplements.

Are there interactions with foods?

There are no known interactions with foods.

What dose is used?

The appropriate dose of peanut oil depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for peanut oil. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
