Move over, coconut oil—there’s a contender stealing the spotlight, and it’s been quietly working its magic for centuries. Castor oil, the thick, golden liquid pressed from the seeds of the Ricinus communis plant. Imagine an ingredient that once lit the lamps in ancient Egyptian temples, soothed Cleopatra’s skin, and has since managed to stay relevant in modern health, beauty, and wellness trends. It’s been whispered about in beauty salons, praised in holistic health circles, and, for many of us, even dreaded as Grandma’s go-to remedy for "cleansing your insides." (Yes, we see you cringing at the memory of those spoonful's.)
But beyond its bold history lies a treasure of benefits. From softening your skin and growing your lashes to soothing aches and sparking new hair growth, castor oil is the jack-of-all-trades your daily routine didn’t know it needed.
Intrigued? You should be. Keep reading, and let’s unravel why this golden elixir is having its long-overdue moment in the spotlight.
SCIENCE: UNCOVERED
Castor oil owes its unique properties to ricinoleic acid, a rare and potent fatty acid that is around 85-90% of plant composition. This natural compound is what gives castor oil its thick consistency and provides its remarkable benefits.
1. Rich in Ricinoleic Acid
Ricinoleic acid in castor oil has a long carbon chain that allows it to penetrate deep into the skin, tissues, and organs. Unlike many other oils, castor oil can pass through the skin's outermost layer, the stratum corneum, and reach the dermis. The dermis, rich in blood vessels and lymphatic connections, acts as a gateway, helping the oil move deeper into the body. This means castor oil can enter the bloodstream, allowing it to be distributed throughout the body for a range of internal benefits.
2. Antibacterial and Antimicrobial Effects
Castor oil primarily acts as an anti-inflammatory agent. It alleviates pain and helps decrease swelling by enhancing lymphatic circulation, and promotes a healthy microbial balance through the stimulation of nitric oxide and the breakdown of biofilms. (Ref.1)
Additionally, it encourages peristalsis by interacting with PGE3 receptors in smooth muscle and offers nutritional benefits through its omega-6 and omega-9 fatty acids, along with vitamin E. (Ref.3)
3. Natural Laxative
Castor oil has a long history of being recognized as a powerful natural laxative. The ricinoleic acid in castor oil interacts with the intestinal walls, promoting smooth muscle contractions that help alleviate constipation. In a study conducted on mice, (Ref. 3) it was discovered that castor oil boosts contractility and peristalsis by activating PGE3 receptors in smooth muscle. Furthermore, research involving rats showed that castor oil supports the production of nitric oxide in the intestines, which may clarify its role in facilitating bowel movements. The influence of castor oil on nitric oxide might also enhance blood circulation in the intestines and provide protective advantages, such as antimicrobial effects and the breakdown of biofilms. (Ref. 1)
4. Hair and Skin
The triglycerides found in castor oil offer excellent conditioning benefits for both hair and skin. Its remarkable ability to deeply penetrate helps to repair damaged hair, strengthen the roots, and alleviate dry, flaky skin. Research (Ref. 2) shows that castor oil is just as effective as capsaicin in reducing inflammation and swelling, but without the irritating effects. It works by stimulating the lymphatic system and easing pain by lowering levels of substance P, a neurotransmitter in the nervous system.
Essentially, if your skin's feeling sore, just apply the oil and let it work its magic—absorbing all those healing benefits straight to where you need them!

Castor Oil Skin Balm Recipe
Melt 1 tbsp beeswax and 1 tbsp coconut oil in a double boiler or in a bowl in a pot of water. Add 2 tbsp castor oil and stir. Once combined, remove from heat and mix in 5-10 drops of your favorite essential oil (like lavender). Pour into a jar and let it cool to form a solid balm. Apply to dry, irritated skin for hydration and relief.
Joint Pain Relief
For joint pain relief, gently massage warm castor oil onto the sore area. Its anti-inflammatory properties can help reduce pain and swelling. For added comfort, wrap the area with a warm towel and leave it on for 20-30 minutes. Repeat as needed for relief.
"The Facelift"
Cleanse: Start by cleansing your face to remove dirt and makeup.

Tap: Lightly tap your face with your fingertips to improve circulation.
Let it Soak: Relax for 10 minutes as the oil nourishes your skin.
