Processing methods on this herb card
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)
Artemisia absinthium — Herbal infusion (tea) (Flower)
About 6 min · Difficulty: Beginner
- Use a very small amount of dried material (well under 1 teaspoon) — wormwood is bitter and strong.
- Pour boiling water, cover, and steep 3–5 minutes.
- Strain — taste check; if too bitter next time shorten the steep or reduce the amount.
Thujone and distilled products have regulated limits — see the herb card; avoid in pregnancy and for children.
Why this way (extraction / behaviour of constituents)
Horká voda a doba louhování řídí uvolňování polárních metabolitů a část těkavých silic; domácí nálev není totéž co standardizovaný čajový extrakt z registrovaných přípravků.

Liquid or paste on the skin, often through a thin cloth.
Full method description (from the catalogue)
A compress applies moist warm or cool material to the skin directly or through fabric. Duration and temperature are key — too hot can burn; too long can macerate the skin.
Use clean textiles and watch skin reaction during the first minutes.
Traditional context for this method: yes·Scientific context for this method: no
Procedure (recipe)
Compress with very weak wormwood infusion
About 20 min · Difficulty: Advanced
- Steep a pinch of dried floriferous material (much less than for tea) in 200 ml boiling water under a lid for 3 minutes, strain, and cool.
- Soak a clean cloth in the cooled liquid and apply to intact skin for at most 10 minutes.
- Do not drink the infusion — wormwood is strong and contains thujone; omit in pregnancy, children, and sensitive states.
Deliberately weak and short contact; stop at once if irritation appears. Spirits and strong internal doses have regulated limits — see the herb card.
Why this way (extraction / behaviour of constituents)
Wormwood is potent and contains thujone-related constituents; a deliberately weak, brief infusion for external compressing is not comparable to concentrated internal products or spirits with regulated limits. Keep contact time short and stop if skin reacts.

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)
Wormwood flower honey (trace amount)
About 30 min · Difficulty: Advanced
- Use a large jar with only a thin layer of dried floriferous material — wormwood is extremely bitter and potent.
- Cover with honey, close, and macerate at most 5–7 days, tasting bitterness; strain early.
- Use only a pinch stirred into honey on toast — not as everyday spoonful honey.
Thujone and spirits are regulated; pregnancy, children, and sensitive states should omit. See the herb card.
Why this way (extraction / behaviour of constituents)
Wormwood is extremely bitter and potent; macerating a small amount of dried flower in honey is not comparable to regulated spirits for thujone and safety limits. Home honey here is a food format with high variability — keep plant material minimal and the maceration time short.
- What is typically released
- Hořké seskviterpenové laktony a další složky přecházejí do medu jen částečně; profil silně závisí na dávce.
- Solvent / water
- Med; macerace maximálně několik dní při kontrole hořkosti.
- After preparation
- Po scedění uchovávej chlazený; při neobvyklé chuti vyřaď.

How to read evidence strength and study type labels
Labels summarise how the catalogue entry is tagged — they are not a medical verdict on efficacy. For every row, read the summary, limitations and source link.
Evidence strength
- Evidence level not specified
- The author did not grade the record; judge from the summary, limitations and source link.
- Narrative / orientational literature
- Descriptive or expert literature without controlled group comparison — context rather than proof of effect.
- Weak evidence
- Study or conclusion with major methodological limits; treat only as a pointer for further reading.
- Preliminary findings
- First or smaller studies — interesting direction, not the final word on efficacy or safety.
- 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.
Study type
- Narrative / expert text
- Expert text or overview without a classical study design.
- In vitro study
- Cell culture or test-tube experiment — does not show an effect in the body.
- Animal study
- Animal model — transfer to humans is not automatic.
- Observational study
- Observing groups without random treatment assignment; confounding is possible.
- Clinical trial
- Human clinical trial; sample size and control group matter.
- Randomised controlled trial
- Randomised controlled trials are among the stronger designs when well conducted.
- Review study
- A review aggregates multiple papers — quality depends on selection rules.
- Systematic review
- Systematic review with explicit search and selection methodology.
- Meta-analysis
- Statistical pooling of studies; outcome depends on input data and heterogeneity.
- Regulatory assessment / monograph (EMA, WHO…)
- Regulatory body summary for a herbal product — different context from a single RCT; often about products, not home tea.
- Expert monograph (herbal preparations)
- Structured literature summary for a plant or drug — quality depends on author and edition year.
Wormwood bitter principles and thujone content are central in pharmacology and toxicology references; absinthe-era consumption patterns do not map to modern tea amounts.
Evidence level not specifiedNarrative / expert textLimitations: Pregnancy and epilepsy cautions; alcohol-based extracts regulated differently from bulk herb; seizure threshold interactions reported for concentrated extracts.
