Traditionally, the dried bark was boiled extensively in water to obtain a concentrated decoction, then cooled and applied as a lotion to affected skin areas. This preparation was reserved for strictly external use. Dosage must be validated with a healthcare professional or recognized pharmacopeia before use.
An alcoholic tincture was sometimes prepared by prolonged maceration of the bark, intended for occasional and localized skin applications. Its preparation and use must be supervised by a professional well-acquainted with this plant. Dosage must be validated with a healthcare professional or recognized pharmacopeia before use.
The bark reduced to fine powder was mixed with a base (vinegar or oil) to form a paste applied locally as a poultice on skin conditions. This traditional practice remains reserved for experienced hands. Dosage must be validated with a healthcare professional or recognized pharmacopeia before use.
Pseudolarix bark is uncommon in the West; it is mainly found from specialists in Chinese pharmacopeia or in herbalist shops specializing in Asian plants. The tree itself is sometimes cultivated as an ornamental conifer in botanical gardens and conifer collections.
Root bark is traditionally harvested in autumn, when the sap descends and the active principles are considered most concentrated.
