Processing methods on this herb card

  • Herbal infusion (tea)(Leaf)Suitability: High suitability

    Infusion or brief extraction in hot water; usually without long boiling.

    Full method description (from the catalogue)

    Here, herbal tea is prepared as an infusion: pour freshly boiling water over dried herbs or a herbal blend and steep for at least 5 minutes. BfR gives this as a hygiene rule, not a medicinal dose. Follow the specific product instructions, including a longer steeping time when stated. This rule for herbal infusions is not a general preparation guide for true tea (Camellia sinensis). Temperature, steep time, and the herb-to-water ratio change both flavour and what dissolves into the liquid.

    Compared with a decoction, heat exposure is shorter and gentler; tender leaves and flowers are often better as an infusion than with prolonged simmering. For each herb, always follow the plant card for suitable plant part, preparation, and safety notes — general rules never replace species-level judgement.

  • Decoction(Root)Suitability: Medium suitability

    Longer simmering of plant material in water.

    Full method description (from the catalogue)

    A decoction is made by simmering plant material in water — often around 10–20 minutes depending on tradition and plant part. Denser parts (roots, bark, some seeds) are often prepared more reliably this way than with a short infusion.

    Compared with an infusion it can extract more compounds, but also more tannins or bitterness; the flavour profile differs from a delicate tea. Combine this overview with the herb card for suitable plant part and contraindications.

  • Tincture(Root)Suitability: High suitability

    Alcoholic or alcohol–water maceration extract.

    Full method description (from the catalogue)

    A tincture is usually a long maceration of plant material in ethanol (sometimes with water). Alcohol and time release different compound groups than hot water alone; concentration and stability depend on the herb-to-solvent ratio and procedure.

    Home production involves legal and safety limits that vary by country; this site gives a general overview, not a recipe. For each herb, read the card for interactions and warnings before preparing anything yourself.
