The Role of Witch Hazel: An Effective Astringent, Not a Disinfectant for the Coronavirus

Introduction

Witch hazel, a popular ingredient in skincare products, has been a topic of discussion in recent years, particularly in the context of its use as a disinfectant against the coronavirus. This article aims to clarify the nature and limitations of witch hazel, emphasizing its true role as an astringent rather than a disinfectant.

Witch Hazel: An Astringent

Witch hazel is renowned for its astringent properties, primarily used for treating minor cuts, scrapes, and various skin irritations. An astringent is a substance that has the power to constrict or tighten the skin, making it ideal for treating open wounds and certain skin conditions like bruises and mild acne.

Natural Properties of Witch Hazel

The astringent effects of witch hazel are attributed to its tannins, natural compounds that impart a drying effect on the skin. Tannins are primarily extracted from the witch hazel plant using a process that includes denatured alcohol. However, the end product of this process typically contains only 14 to 15% alcohol, far below the required 60% or more to effectively kill viruses like the coronavirus.

Disinfectant Recommendations

The efficacy of disinfectants against viruses such as the coronavirus is contingent on their alcohol content and sophistication in chemical composition. According to the World Health Organization (WHO) and other health authorities, a minimum of 60% alcohol is crucial for effective disinfection. Therefore, it would be inaccurate to use witch hazel as a primary means of disinfection for the coronavirus.

The Best Prevention Strategy

While witch hazel plays an important role in skincare, the most effective way to protect oneself against the coronavirus remains regular hand washing with soap and water. According to the Centers for Disease Control and Prevention (CDC), hands should be washed for at least 20 seconds to effectively remove germs.

Further Recommendations

In addition to hand washing, other precautionary measures include avoiding close contact with sick individuals, covering coughs and sneezes, and regularly cleaning and disinfecting frequently touched objects and surfaces.

Conclusion

While witch hazel is a valuable component in a skincare routine, it should not be considered a disinfectant for the coronavirus. For thorough and effective disinfection, alcohol-based hand sanitizers or other recognized disinfectants with appropriate alcohol content are recommended. Proper hand hygiene remains the cornerstone of preventing the spread of the virus.
