Ingredient: Masterwort Leaf Extract

Botanical Name: Peucedanum ostruthium (also known as Imperatoria ostruthium)

  • Peucedanum - Derived from the Greek word for parsnip, peukedanon

  • Ostruthium - Derived from the Greek name ostranthium which means "supreme strength"

What it is: Masterwort is a perennial flowering plant native to the mountains of Central and Southern Europe that is now grown widely around the world. It’s a member of the Apiaceae family and a relative of the carrot, parsley, parsnip, and celery.

What it does: Masterwort has been a medicinal staple since the Middle Ages referred to as “the divine remedy” by the Romans, “the Queen of the plants” by the Swiss, and “the magic plant” by others. It’s no wonder this plant has such flattering monikers — over the past few centuries, it has been used to restore vision and youth, for wound healing, to flavor malt beer and liquor, to help with digestion, for toothaches and migraines, for respiratory and cardiovascular problems, and for infections, colds, flu, and fevers. It’s a true wonder of nature!

What caught our eye was Masterwort’s skin benefits. Being native to the Swiss Alps, the plant protects itself from the harsh natural conditions by producing flavonoids and phenolic acid, which are also incredibly beneficial in helping soothe and protect skin. There’s even evidence that components in the plant stimulate cellular regeneration and restore cell function, as well as help repair stressed skin and relieve skin irritation. Sounds perfect for a skin product, right?

Why we use it: In addition to its naturally healing and protective qualities, it’s a completely natural, renewable resource. We love finding gifts from nature that are not only effective, but are also easy to source and take relatively little effort to process into a raw ingredient for commercial use!
