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)

    In the narrow sense, “tea” often means an infusion: you pour water just off the boil over the dried plant matter and let it steep for a few minutes. 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.

    Traditional context for this method: yes·Scientific context for this method: no

    Procedure (recipe)

    Peppermint leaf tea

    About 10 min · Difficulty: Beginner

    Extraction parameters (rough guide): 250 ml water · 95–100 °C · 5–10 min steep

    1. Place 1–2 teaspoons of dried leaf or one larger sprig of fresh mint in a cup.
    2. Pour about 250 ml of water at roughly 90–95 °C, then cover.
    3. Steep 5–8 minutes and strain. For a milder flavour, shorten the steep — peppermint can be quite intense.

    If you have reflux or are sensitive to menthol, consider limiting use; not a substitute for medical care.

    Why this way (extraction / behaviour of constituents)

    The HMPC monograph on peppermint mentions traditional use for dyspeptic complaints and reflux as a safety topic; a home tea may still irritate the oesophagus in sensitive people at high menthol concentration. Shorter steeping often keeps a fresher, lighter profile.

    What is typically released
    Menthol a flavonoidy v nálevu.
    Solvent / water
    Voda.
    After preparation
    Čerstvě.

  • Honey macerate(Leaf)Suitability: High suitability

    Macerating plant material in honey (a honey conserve).

    Full method description (from the catalogue)

    Honey as a maceration medium creates a viscous mixture with its own biochemistry: water activity, acidity, and enzymes influence shelf life and flavour. Traditionally it is used with delicate flowers or herbs when you want aroma bound into honey.

    Infant botulism guidance for honey and honey safety in general sit outside a single herb page; maceration time, ratios, and storage must follow a vetted recipe and source, not this general overview alone.

    Traditional context for this method: yes·Scientific context for this method: no

    Procedure (recipe)

    Peppermint honey

    About 30 min · Difficulty: Beginner

    1. Fill about one third of the jar with dried or fresh leaves, pour runny honey over them, and press so little air stays trapped.
    2. Close and macerate 2–3 weeks in a warm shady place, shaking occasionally.
    3. Strain through cloth; use in tea or yoghurt — menthol notes can be strong.

    Maceration takes weeks; use modestly if you have reflux or menthol sensitivity.

    Why this way (extraction / behaviour of constituents)

    Home preparation following this recipe is mainly educational and cultural; it should not be assumed to match the extractive or safety profile of registered medicines or standardized extracts. Check specific effects, drug interactions, and contraindications on the herb card and with your clinician if you use prescription drugs.

    Extra literature for the recipe

  • Syrup(Leaf)Suitability: High suitability

    Decoction or infusion with sweetener and reduction; shelf life depends on sugar and storage.

    Full method description (from the catalogue)

    Syrups combine a herbal base with sugar or honey and often a short boil to concentrate and improve hygiene. Preservation depends strongly on water content, sugar level, and bottling practice.

    Home syrups may fall under food rules; store in the fridge after opening per recipe.

    Traditional context for this method: yes·Scientific context for this method: no

    Procedure (recipe)

    Peppermint syrup

    About 35 min · Difficulty: Beginner

    Extraction parameters (rough guide): 350 ml water · 95–100 °C · 6–10 min steep

    1. Steep 2 tsp dried leaf in 350 ml boiling water under a lid for about 8 minutes, then strain.
    2. Stir in honey or sugar and warm briefly.
    3. Store refrigerated; dilute more if you have reflux.

    Why this way (extraction / behaviour of constituents)

    Same principle as other leaf syrups: hot-water extraction followed by sugar or honey preservation. Menthol and other volatiles partly escape with steam — shorter steeping often keeps a fresher profile than long boiling.

    What is typically released
    Silice a polární frakce v předslazeném nálevu.
    Solvent / water
    Voda jako první krok; sladidlo po scedění.
    After preparation

  • Essential oil(Leaf)Suitability: High suitability

    Steam-distilled highly aromatic oil; requires dilution and respect for potency.

    Full method description (from the catalogue)

    Essential oil is a highly concentrated product of steam distillation (or other approved methods). A single drop can be plenty; topical use normally requires dilution in a carrier oil using established ratios.

    Never apply strong neat oil to large areas without knowing irritancy.

    Traditional context for this method: yes·Scientific context for this method: yes

    Procedure (recipe)

    Peppermint / menthol essential oil

    About 10 min · Difficulty: Beginner

    1. Industrially distilled menthol or peppermint EO is diluted in carrier oil or used on an inhaler wand — home distillation without apparatus does not match commercial profiles.
    2. Typical dilution about 1–5 % by purpose; neat EO irritates skin and mucous membranes.

    Why this way (extraction / behaviour of constituents)

    Home preparation following this recipe is mainly educational and cultural; it should not be assumed to match the extractive or safety profile of registered medicines or standardized extracts. Check specific effects, drug interactions, and contraindications on the herb card and with your clinician if you use prescription drugs.

    Extra literature for the recipe

  • Inhalation(Leaf)Suitability: High suitability

    Breathing steam from a herbal infusion; mind temperature and irritants.

    Full method description (from the catalogue)

    Steam inhalation brings moisture and dissolved volatiles toward upper-airway mucosa. Temperature must be safe — distance above the bowl or a dedicated inhaler reduces scald risk.

    Keep first sessions short; stop if dizzy.

    Traditional context for this method: yes·Scientific context for this method: no

    Procedure (recipe)

    Steam from peppermint

    About 15 min · Difficulty: Beginner

    1. Put a handful of dried leaf in a bowl, pour hot (not boiling) water, cover your head with a towel, and inhale 5–8 minutes.
    2. Keep a safe distance from the water — steam burns matter; children only with supervision.

    Check with a doctor before strong steam inhalation if you have asthma.

Moderate strength of evidence
Moderate strength by study design; sample and context limits still apply.
Stronger evidence
Stronger design or consistency of results within the study’s stated limits.
Review article
A review summarises multiple sources; quality depends on review method and field.
