There is no evidence that anthralin can prevent novel coronavirus infection. The main ingredients of essential oils are menthol, methyl salicylate, camphor, eucalyptus oil and eugenol. There is no evidence that these substances can kill novel coronaviruses, so they cannot play an effective preventive role. The more readily available substances that residents can use to destroy the virus remain alcohol. However, people are home for long periods of time and may consider using windex occasionally to refresh themselves.
