Castor oil has been used for centuries as a traditional folk remedy for various ailments. Recently, applying castor oil specifically to the belly button has gained popularity as a "hack" for boosting health. But is there any proof behind the buzz? As a natural health expert, I decided to investigate…
A History of Healing
Documented medical use of castor seeds and oil dates back to ancient Egypt. Traditional Ayurvedic practices in India have also utilized castor oil as an internal and external treatment for conditions like arthritis, constipation, infections and more [1].
Folk healers prescribe applying warm castor oil directly on the skin to improve blood circulation and relieve pain. Specific belly button (navel) application has roots as an old-wives remedy for digestive issues.
This suggests a longstanding traditional belief in castor oil‘s absorptive abilities, especially centered on the navel region. Modern applications thus build on these ancestral healing customs.
Proposed Mechanisms: Why the Belly Button?
The belly button area contains numerous nerve endings that connect to organ systems throughout the body. Some alternative practitioners believe substances get rapidly absorbed into bloodstream when applied here.
Anatomically, the umbilicus is a scar from when arteries/veins connected through the abdomen during development in the womb. A "naval chakra" also figures in some esoteric healing arts [2].
While unproven, these ideas offer insight on why castor oil may interact uniquely with the navel region. More research is needed to verify any distinct absorption mechanisms scientifically.
Review of Evidence on Castor Oil Benefits
Castor oil contains ricinoleic acid which gives its potent therapeutic actions [1]. When applied topically, it acts as an anti-inflammatory and improves circulation. Internal use as a laxative also makes it useful for constipation relief.
But what does the data say about castor oil specifically for belly button use? Let‘s analyze key areas claimed:
Weight Loss
Some proponents posit that rubbing castor oil here boosts metabolism and fat burning through faster nutrient absorption [3]. But current studies are unavailable to validate such weight-loss effects.
