🌿 Castor Oil

Traditional wellness oil for external care—composition, uses, and sourcing.

⚠️ EXTERNAL USE ONLY (Historical oral laxative use only under professional guidance)

Overview

Castor oil is a thick, viscous oil pressed from the seeds (beans) of Ricinus communis. Used for thousands of years in traditional wellness practices, castor oil is primarily applied externally for skin care, hair care, and therapeutic massage. The oil is rich in ricinoleic acid, a rare fatty acid with unique properties. Note: Castor oil is NOT intended for internal consumption in typical wellness use.

SuperfoodSpace Disclosure

SuperfoodSpace Disclosure: This product is traditionally used as external (cosmetic and therapeutic applications). Castor oil has historical use as an oral laxative but is harsh and should only be taken internally under professional guidance. Most modern applications are external and not intended for ingestion. Individual tolerance may vary. Consult a qualified professional before use if you are pregnant, nursing, taking medications, or managing a medical condition.

Typical origins & sourcing

Castor oil is produced in tropical and subtropical regions worldwide. Prioritize:

  • Primary sources: India (largest producer), Africa, South America, Middle East.
  • Cold-pressed: preserves ricinoleic acid and beneficial compounds.
  • Organic certification: ensures no pesticides (castor plant accumulates toxins).
  • Hexane-free: avoid chemical extraction methods.
  • 100% pure: no additives, fillers, or synthetic ingredients.
  • Dark glass bottles: protects oil from light degradation.
  • Color indicator: pale yellow to golden (quality varies by processing).

Storage tip: Store in cool, dry place away from direct sunlight. Shelf life is 1-2 years. Does not typically need refrigeration due to thick consistency.
