rubbing castor oil on thyroid

Rubbing castor oil on the thyroid may seem like an unusual recommendation for those seeking to improve their thyroid health, but it has a history of use in alternative medicine and has been the subject of recent studies. This practice is based on the principle that castor oil, due to its high content of ricinoleic acid, has anti-inflammatory and soothing properties that may benefit the thyroid gland.

What Is Castor Oil?

Castor oil is derived from the castor bean plant, Ricinus communis, and contains mainly ricinoleic acid, which is a monounsaturated fatty acid. This acid gives castor oil its therapeutic properties and has been used traditionally for various purposes, including treating skin conditions and improving digestion.

Thyroid Gland Function

The thyroid gland is a butterfly-shaped organ located low in the front of the neck that produces hormones that regulate metabolism, heart rate, and temperature. It plays a crucial role in the body's thyroid hormone, which influences growth, development, and other critical body functions.

Health Concerns with the Thyroid

Thyroid disorders, which include hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), can lead to a range of health issues, from goiters to more serious conditions. Hashimoto's thyroiditis, an autoimmune disease, is a common cause of hypothyroidism and results in progressively weakening thyroid function.

Traditional Uses of Castor Oil

Castor oil has been used traditionally for various purposes, including soothing skin conditions, as a lubricant for joints, and for various skin conditions and wounds. It has been used in Ayurvedic medicine for various conditions, including respiratory diseases, skin diseases, and eye diseases.

Recent Research on the Thyroid

Recent research has investigated the potential benefits of castor oil for thyroid health, finding that it may have anti-inflammatory properties that could benefit Hashimoto's thyroiditis and reduce inflammation around the thyroid gland. Researchers have also explored the use of castor oil packs applied to the skin over the thyroid area to potentially improve circulation and hormone production.

How to Use Castor Oil

Using castor oil on the thyroid can be as simple as applying the oil directly onto the skin or using it in a pack. Applying the oil directly can help the body absorb it more easily, while a castor oil pack can be applied over the thyroid area with a hot water bottle or heating pad to soothe the skin and enhance absorption.

Potential Risks

While castor oil may have health benefits, it is important to be aware of potential risks and side effects. Some individuals may experience skin irritation or an allergic reaction, and it is always advisable to start with a small amount and observe how your body reacts before increasing the dosage.


Rubbing castor oil on the thyroid is a practice with a long history and some supporting evidence for its potential benefits for thyroid health. However, it is important to consult with a healthcare provider before starting any new health regimen and to monitor how your body reacts to ensure safety.
