Symphytum Officinale Comfrey Root Oil
What is Symphytum Officinale Comfrey Root Oil?
Symphytum Officinale Comfrey Root Oil is extracted from the roots of the comfrey plant (Symphytum officinale), a perennial herb native to Europe and parts of Asia, traditionally used in herbal medicine for its soothing properties. Rich in allantoin, mucilage, and rosmarinic acid, it is employed in skincare for its potential to promote skin regeneration and reduce inflammation. However, its use is controversial due to the presence of pyrrolizidine alkaloids (PAs), which are hepatotoxic and potentially carcinogenic when absorbed systemically.
Roles in Formulation

Emollient
Softens and smooths skin by filling in surface roughness and improving slip; can also help reduce moisture loss when paired with occlusives and film formers.
Antifungal agent
Inhibits fungal growth on skin/scalp or within the product, supporting stability and helping manage fungal-related concerns depending on the application.
Skin conditioning agent
Maintains skin softness, smoothness, and flexibility.
Soothing
Helps reduce the feeling of discomfort and visible irritation by supporting skin calmness, often through anti-irritant, barrier-supporting, or cooling mechanisms.
Antimicrobial agent
Helps limit growth of bacteria and other microbes on skin or in the formula; may be used for product protection, odor control, or targeted antimicrobial effects.
