Berberine is a bioactive compound, an alkaloid, extracted from plants like goldenseal and barberry. It has a distinct yellow color and a history of use in traditional medicine for various ailments. Recently, the idea of using berberine in homemade eye drops has gained traction, largely through discussions on social media platforms. This trend has raised questions about its safety and effectiveness for ocular use.
The Claims and Origins of the Trend
The trend of using homemade berberine eye drops is driven by social media, where users share videos and testimonials claiming a range of benefits. These posts often feature dramatic before-and-after images, contributing to the trend’s viral spread. The accessibility of berberine supplements makes it easy for people to create their own solutions at home.
The primary claim fueling this trend is that berberine can change a person’s eye color, supposedly by altering the melanin levels in the iris. Other purported benefits include treating eye infections such as conjunctivitis, reducing eye redness, and alleviating symptoms of dry eye. These claims are presented as a natural and effective alternative to conventional medical treatments.
The narrative often positions berberine as a ‘natural’ remedy, which appeals to those seeking alternatives to pharmaceutical products. The historical use of berberine in traditional medicine is sometimes cited to lend credibility to these claims. However, the online discourse rarely distinguishes between oral consumption of berberine for systemic health issues and the direct application of a homemade solution to the delicate tissues of the eye.
Scientific Evidence for Berberine in Eye Health
In laboratory and animal studies, berberine has demonstrated properties that could be relevant to eye health. Research has shown that berberine possesses anti-inflammatory, antimicrobial, and antioxidant effects. For instance, some test-tube and animal studies suggest it can reduce the growth of various microorganisms and combat oxidative stress, which is implicated in several eye conditions.
Further research in animal models of diabetic retinopathy has explored berberine’s potential protective effects. Studies on rats with induced diabetic retinopathy indicated that berberine could reduce cell apoptosis and oxidative stress in the retina. Another study on isolated animal lenses suggested a potential role in counteracting processes that lead to diabetic cataracts.
These investigations do not support the use of homemade berberine eye drops. The studies involved purified berberine, often administered orally or through other systemic routes in animal models, or applied to cells in a controlled lab setting. There is no scientific evidence that applying a non-sterile, homemade berberine solution to the human eye is safe or effective.
Risks and Professional Medical Guidance
The practice of using homemade berberine eye drops carries significant risks. The American Academy of Ophthalmology has issued warnings against using unregulated, over-the-counter eye drops, including those containing berberine, due to the potential for serious eye damage. These products are not approved by the FDA, meaning they have not been tested for safety, efficacy, or purity.
A primary danger is the formulation. Homemade solutions are not sterile and can become contaminated with bacteria, fungi, or other pathogens, leading to severe infections that could result in vision loss. An incorrect pH balance can also cause chemical burns to the cornea, the transparent outer layer of the eye.
Furthermore, if the berberine powder is not fully dissolved, the undissolved particles can act as abrasives, causing scratches on the corneal surface known as corneal abrasions. These abrasions are painful and create an entry point for infection. The long-term effects of applying berberine directly to the eye are unknown, but potential consequences include chronic inflammation, increased intraocular pressure (glaucoma), and permanent damage to the delicate structures of the eye.
Understanding Eye Color and Health
The claim that berberine eye drops can change eye color is not supported by biology, as eye color is a complex genetic trait. It is determined by the amount and distribution of melanin within the iris. Attempting to change eye color with unregulated drops could instead damage the pigmented cells of the iris, potentially leading to light sensitivity and inflammation.
For common eye complaints like redness or dryness, there are safe and medically approved options available. Over-the-counter lubricating eye drops, often labeled as artificial tears, are sterile and specifically formulated to provide relief without causing harm. These products can help to soothe irritation and supplement the eye’s natural tear film.
If symptoms like redness, dryness, or signs of an infection persist, consult an ophthalmologist or optometrist. They can properly diagnose the underlying issue and recommend appropriate treatments. These may include prescription eye drops, lifestyle adjustments, or other therapies proven to be safe and effective.
