symphytum officinale leaf tincture

Symphytum officinale leaf tincture is an extract obtained from the leaves of the comfrey plant, Symphytum officinale, a species with long-standing traditional uses. This tincture appears as a liquid with a mild woody and rooty odor at full concentration. It is synonymous with terms such as comfrey leaf tincture and quaker comfrey leaf tincture. The material is classified under chemical abstracts service number 84696-05-9 and indexed on public chemical databases such as PubChem. It is typically sourced by solvent extraction of comfrey leaves, yielding a product primarily intended for informational and research purposes. This tincture is not commonly incorporated in fragrance or flavor formulations.

Symphytum officinale leaf tincture naturally occurs as a botanical extract from the comfrey plant, which thrives in Europe and parts of Asia. The tincture captures aromatic and phytochemical constituents characteristic of the comfrey leaf. Its documented applications are informational only; it is not approved or recommended for use in fragrance or flavor products according to current industry guidelines. In regulatory contexts, the tincture is referenced within REACH (EU) frameworks for chemical registration and information sharing. Although historical traditional uses exist for comfrey extracts, this tincture serves primarily as a subject of chemical and safety data rather than a direct commercial ingredient in sensory formulations.

Symphytum officinale leaf tincture presents with a specific gravity ranging between 1.001 and 1.06 at 25 °C, indicating slight density variations typical of botanical tinctures depending on solvent concentration and extraction parameters. The tincture exhibits a mild woody rooty odor profile at 100% strength, a sensory attribute relevant for characterization but not exploited commercially in perfumery or flavoring. Its physical state as a liquid around ambient temperature affords ease of handling in laboratory contexts. Chemical stability and miscibility parameters are inferred to align with typical plant-based tinctures but precise data on volatility or solubility beyond specific gravity are limited. No classifications under formal hazard communication standards have been identified.
