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.

Similar herbs
- Ginger
Similar rhizome shape; galangal is paler, harder, with pink-edged shoots and a resin-and-pine scent, ginger is beige and hot.
- Fingerroot
Fingerroot (krachai) has a bunch of thin finger-like rhizomes and a milder taste; Thai cooking uses it in different dishes.
- Kencur
Kencur (Kaempferia) is a small, round, camphor-scented rhizome of Indonesian cooking — a different genus despite the shared name 'galanga'.

Harvest
- RhizomeNovember–February
zima
Region: ThailandNotes: Rhizomes are dug 10–12 months after planting, in the dry season; young pink-edged rhizomes are the tender ones for cooking, older tough ones are dried and sliced.
Storage
- Refrigeration(Rhizome)
Fresh rhizome keeps 2–3 weeks in the fridge in paper; sliced it freezes very well and goes into soup straight from the freezer.
- Moisture:
- Moulds in sealed plastic.
- Drying(Rhizome)
Dried slices keep 12–18 months in a closed container; soak before use.
- Light:
- Out of light.

Processing methods on this herb card
Cooking, baking, seasoning as food — general category without therapeutic claims.
Full method description (from the catalogue)
Culinary use covers herbs as ingredients in dishes, drinks, or spice mixes. This overview does not evaluate medicinal effects — only reminds you about species intent, allergies, and heat treatment where needed (e.g. some fruits or plant parts).
Combining with alcohol, sugar, or long cooking changes outcomes; verify culinary sources.
Traditional context for this method: yes·Scientific context for this method: no
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.
Traditional context for this method: yes·Scientific context for this method: no
Finely ground dried herb; dosing and solubility depend on species.
Full method description (from the catalogue)
Powder increases surface area for liquids or food. Home milling needs a clean grinder and control of fineness; very fine powder may clog tea filters.
Store airtight against moisture and pests.

Hildegard's 'spice of life'
General
Historical mentionFolk useHerbal loreHildegard of Bingen (12th century) recommended galangal in her Physica against weakness of the heart and as an all-round 'warming' spice; later tradition named it the 'spice of life'. Medieval galangal, however, was most likely the lesser species Alpinia officinarum from China, not Thai A. galanga — the link to today's plant is loose. A historical record.

- Historical mention
- Source note:
- Hildegard of Bingen, Physica I, 13 (Galgan); the species identity of medieval galangal is uncertain.
Scientific notes
Each claim lists a study type and a source (URL or DOI) where available. Dose notes from the literature are informational only.
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.

Safety
What the warning types mean
The type on each warning helps group themes — it does not replace the separate severity badge.
- Internal use
- Risks from swallowing, extracts, duration of use or concentration for internal use.
- Interactions / medicines
- Possible effect on medicines or concurrent treatment — check sources and a professional.
- Raw plant parts
- Raw, unripe or poorly prepared plant parts can be dangerous.
- Toxins and regulation
- Toxic constituents or regulated compounds (e.g. in distillates).
- Contact with the plant
- Skin or mucosa irritation from contact with fresh plant or sap.
- Allergy
- Allergic reactions, often linked to family sensitisation.
- Harvesting and contamination
- Contamination, species mix-ups or harvesting from unsuitable places.
