STILLINGIA SYLVATICA ROOT.

Avoid CAS 90131-35-4 / SKIN CONDITIONING - EMOLLIENT

Stillingia Sylvatica Root, historically known as Queen's Delight, is traditionally recognized for its purported stimulating and detoxifying properties in various remedies. While once applied topically for certain skin conditions, its phytochemical profile includes potent irritant compounds that pose significant safety concerns for dermal use within precision skincare.

Summary

Science

Mechanism of Action

Traditionally, Stillingia sylvatica root was considered a stimulating alterative, believed to promote detoxification by enhancing the activity of the liver, lymph nodes, and excretory systems. Historically, it saw topical application for conditions like chronic skin eruptions, eczema, and acne, purportedly by supporting lymphatic drainage. However, its phytochemistry reveals diterpenes, resins, volatile oils, and, critically, diterpene esters, which are identified as toxic irritants capable of causing swelling and inflammation upon skin contact. Some *in vitro* studies on *other Stillingia species* have indicated antioxidant and antifungal properties, but these findings do not directly confirm efficacy or safety for *S. sylvatica* in human skin application.

Stability

The root is most active when fresh and significantly diminishes in 'medicinal virtue' with age. Preparations made from older, degraded material have shown a lack of therapeutic effect. Dried root pieces should be stored in an airtight container in a cool, dry place, and should not be stored in plastic to prevent mold formation.

Safety

Safety Profile

CIR Status
Not reviewed
Sensitization risk High

Stillingia sylvatica root contains diterpene esters, which are classified as toxic irritants known to induce mucosal irritation, swelling, inflammation, and skin eruptions. The latex present in the plant's sap has been observed to cause skin blistering. This ingredient is considered potentially harsh and toxic, especially in high concentrations or with prolonged exposure. Products containing Stillingia root have not undergone evaluation by the FDA and are not sanctioned for medical treatment or cure of diseases, lacking scientific evidence for such claims.

Verdict

Avoid

Given its documented high irritancy, presence of toxic diterpene esters, and complete lack of clinical efficacy data for safe topical application, Stillingia Sylvatica Root is not suitable for precision skincare formulations.
