@enhancedhealthuk Putting a castor oil pack over your thyroid can help to reduce toxins and regulate inflammation. Castor Oil Packs have also been shown to help with swelling around the thyroid gland and reducing the size of thyroid nodules. HOW CAN CASTOR OIL PACKS SUPPORT THE THYROID? Lymphocytes are your immune system’s disease-fighting cells and are produced and stored mainly in your lymphatic tissue. This is where castor oil comes in. When castor oil is absorbed through your skin (according to Cayce and McGarey) your lymphocyte count increases. Increased lymphocytes speed up the removal of toxins from your tissues, which promotes healing. One-third of your lymph is located in the neck and into the brain. Your thyroid is also located in your neck, so putting a castor oil pack over the thyroid can help improve blood fl ow, bring more oxygen and nutrients to the tissues, reduce swelling, and remove toxins.
