2,6-di-tert-butyl-p-creosol, BHT, Butil Hidroxitolueno, Butylated Hydroxytoluene, Butylhydroxytoluene, Butylhydroxytoluène, Butyl Hydroxytoluène, Dibutylated Hydroxytoluene, Dibutylhydroxytoluène, Hydroxytoluène Butylé.
BHT (butylated hydroxytoluene) is a lab-made chemical that is added to foods as a preservative. People also use it as medicine.
Some people apply BHT directly to the skin for cold sores.
How does it work?
BHT is an antioxidant. It may damage the protective outer layer of viral cells. This may keep the viruses from multiplying and/or doing more damage.
Insufficient Evidence to Rate Effectiveness for...
- Cold sores caused by a type of virus called herpes. Developing evidence suggests that putting BHT on cold sores may help them heal faster.
- Genital herpes.
- Acquired immunodeficiency syndrome (AIDS).
- Other conditions.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
The appropriate dose of BHT depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for BHT. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
