Harvest

  • LeafJanuary–December

    celoročně

    Region: India

    Notes: Whole pinnate leaves are snapped from the tree throughout the year, most in the rainy season; they go to the kitchen fresh, drying loses most of the aroma.

Storage

  • Refrigeration(Leaf)

    Fresh sprigs keep 1–2 weeks in the fridge in paper; the leaflets can be frozen in a bag and used straight from the freezer.

    Moisture:
    They blacken in sealed damp plastic.
  • Drying(Leaf)

    Dried leaflets keep 6 months in a closed container; the aroma is weak, suitable for spice blends and hair oil, not as a stand-in for fresh.

    Light:
    Out of light.
    Moisture:
    Protect from moisture.

Processing methods on this herb card

  • Culinary use(Leaf)Suitability: High suitability

    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

  • Herbal oil(Leaf)Suitability: Medium suitability

    Macerating herbs in a vegetable oil (cold or with gentle heat).

    Full method description (from the catalogue)

    Herbal oil is made by steeping dried or fresh material in oil (e.g. olive, sunflower) over time, sometimes with gentle warming. The result is not steam-distilled essential oil — it is a different extract type and usage (often topical or culinary per recipe).

    Temperature, light, and material moisture affect shelf life; rancid oil must be discarded.

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

    Curry-leaf hair oil is a South Indian cosmetic tradition; external use, not for eating.

    General

    Traditional useFolk remediesFolk use

    In Tamil and Kerala household tradition curry leaves are simmered in coconut oil for a hair oil against greying and hair loss and added to everyday food 'for digestion'; the tree grew by every house and women wove the leaves into their hair. A record of folk cosmetics and cooking, not a proven effect.

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.
