FAQ
Frequently Asked Questions
No, it's historically misnamed. It is obtained from the Myroxylon balsamum tree, which is native to Central America (primarily El Salvador), not Peru.
Traditionally, it was used as a medicine for wounds and coughs. Today, its main uses are as a fragrance and flavouring agent, and it is critically important as a standard allergen in dermatological patch testing.
Most commonly, a dermatologist or allergist would mention it when diagnosing allergic contact dermatitis, as it is one of the most common fragrance allergens tested for.
For the general population, it is safe in the small quantities used in products. However, for individuals who have developed a sensitivity to it, exposure can cause significant skin irritation (allergic contact dermatitis).
