What Are Castor Oil Packs?

Castor oil packs involve applying organic castor oil to a piece of cloth (typically wool or flannel), placing it on the body, and for extra benefits you can cover it with heat to allow the oil to penetrate deeper into the skin. It’s a soothing, gentle practice that supports so many functions in your body.

Castor oil, derived from the seeds of the castor plant (Ricinus communis), is rich in ricinoleic acid, which is known for its anti-inflammatory and detoxifying properties.

10 Benefits of Castor Oil Packs

  1. Supports Lymphatic Drainage – Encourages the movement of lymph fluid, helping the body eliminate toxins more efficiently.

  2. Liver Detoxification – Promotes circulation to the liver and assists in flushing out built-up waste.

  3. Improves Digestion – Applying castor oil to the abdomen can help relieve constipation and support overall gut function.

  4. Balances Hormones – Especially helpful in supporting estrogen detox and regulating the menstrual cycle.

  5. Reduces Inflammation – Castor oil contains ricinoleic acid, which has natural anti-inflammatory properties.

  6. Relieves Pain – From menstrual cramps to joint discomfort, castor oil packs can soothe pain and tension.

  7. Boosts Circulation – Improves blood flow to vital organs and tissues.

  8. Enhances Immune Function – A well-drained lymph system and detoxed liver are critical for immunity.

  9. Improves Sleep – Many report deeper, more restful sleep after regular use.

  10. Fertility Support – Helps improve circulation and reduce pelvic congestion for those trying to conceive.
