- 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.

Identification and mix-ups
A perennial herb with upright to reclining stems and leaves divided into three leaflets. The leaflets are broadest towards the tip to nearly round, often with a pale marking; its absence alone does not rule out the species. The stipules at the leaf base narrow abruptly to a fine, bristle-like point. The flower heads are rounded to oval, stalkless and closely supported by a pair of leaves. Flowers are usually pink to purple, occasionally whitish. For identification, consider the leaves, stipules and position of the heads together; pink colour alone is not enough.
Possible mix-ups and risks
Hybrid clover and fodder clovers.

Processing methods on this herb card
Infusion or brief extraction in hot water; usually without long boiling.
Full method description (from the catalogue)
Here, herbal tea is prepared as an infusion: pour freshly boiling water over dried herbs or a herbal blend and steep for at least 5 minutes. BfR gives this as a hygiene rule, not a medicinal dose. Follow the specific product instructions, including a longer steeping time when stated. This rule for herbal infusions is not a general preparation guide for true tea (Camellia sinensis). 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.

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
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.
