Castor oil packs are a topical application believed to support thyroid function by stimulating lymphatic drainage, reducing inflammation, and enhancing detoxification. Follow this concise protocol:
Materials Needed
- Cold-pressed, hexane-free castor oil
- Flannel or wool cloth (cut to cover neck area)
- Plastic wrap or reusable waterproof pad
- Hot water bottle or heating pad
- Old towels and clothing
Application Steps
1. Prepare the Pack: Saturate flannel with 1-2 tbsp castor oil until damp but not dripping.
2. Position: Lie down and place the oiled cloth directly over the thyroid gland (lower front neck, below Adam's apple).

3. Cover & Heat:
- Layer plastic wrap over the pack extending beyond cloth edges
- Place hot water bottle/heating pad on low setting over plastic
- Cover with towel for insulation
4. Duration: Retain for 45-60 minutes. Perform 3-4 times weekly for 4 weeks minimum.
Safety Considerations
- Avoid if pregnant, breastfeeding, or with open skin wounds
- Discontinue if rash or discomfort occurs
- Test for skin sensitivity on small area first
- Never ingest castor oil during this procedure
Post-Treatment: Wipe skin with baking soda solution (1 tsp soda + 2 cups water), then wash with soap. Store used pack in sealed container for reuse (up to 30 applications). Supplement with hydration and thyroid-supportive nutrients like selenium and zinc for synergistic effects. Clinical research remains limited; consult your healthcare provider regarding thyroid conditions.
