What the safety levels mean (expand legend)
- Generally recognised as safe. Often a common herb with reasonable harvest and use; still read the specific warnings on the card.
- Information. Primarily informational — details in the text and warnings below matter most.
- Caution. Needs extra care (dose, duration, sensitive groups, interactions).
- Risky. Significant risks — verify sources, contraindications and professional guidance.
- Not for home experimentation. Not suitable to experiment with at home without knowledge and certainty.
- High risk for internal use. Particular risk with internal use (e.g. alkaloids); avoid prolonged or irresponsible dosing.
- Not specified. Level not filled in yet — rely on individual warnings and links below.

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)
Common thyme infusion
About 8 min · Difficulty: Beginner
Extraction parameters (rough guide): 250 ml water · 95–100 °C · 6–12 min steep
- Use 1 teaspoon of dried herb per cup (thyme is potent).
- Pour boiling water, cover, and steep 5–8 minutes.
- Strain — try a shorter steep if the taste is too intense.
Why this way (extraction / behaviour of constituents)
The HMPC text on thyme herb describes traditional use in preparations for productive cough; a home tea has no standardized thymol level or extraction ratio. A very strong or long infusion may irritate the stomach.
- What is typically released
- Silice a taniny podle délky louhování.
- Solvent / water
- Voda.
- After preparation
- Čerstvě.

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)
Thyme syrup
About 45 min · Difficulty: Beginner
- Steep 2–3 tsp dried tops in 400 ml boiling water under a lid for about 20 minutes, then strain.
- Add about the same volume of sugar or honey and warm gently to dissolve without a hard boil.
- Bottle and store refrigerated; dilute to taste.
Strong aromatic herb — start with a small diluted dose; mind sugar with diabetes.
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.

- orientační domácí extrakce — profil závisí na teplotě, času řezu a poměrech
- Solvent / water
- mediální složení (voda, alkohol, olej, med…) viz jednotlivé kroky
- After preparation
- po přípravě uchovávej hygienicky a podle typu výrobku (chlad, světlo, alkohol)

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)
Thyme honey
About 30 min · Difficulty: Beginner
- Fill about one quarter of the jar with dried tops and cover with honey.
- Macerate 2–3 weeks, then strain — very aromatic.
Maceration takes weeks; start with a small amount.
Why this way (extraction / behaviour of constituents)
Thyme contains phenolic volatiles (thymol, carvacrol) that partly move into honey; strongly aromatic plant material calls for restraint. A macerate is a home food, not an inhalational or pharmaceutical preparation.
- What is typically released
- Silice a polární antioxidanty částečně v medu.
- Solvent / water
- Med; macerace 2–3 týdny.
- After preparation
- Po scedění chladně.

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.
