A little about hawthorn berry & leaf.

The plant

Berries are mild, apple-tart, and mealy-sweet. Native to Europe, Northwest Africa & Western Asia (Rosaceae (Rose Family)).

The forms

Most often prepared as a simmered berry decoction using 5 g (1 tbsp whole dried berries) at 205°F–212°F covered simmer (Simmer 15–20 min in 10 oz water (or steep 8 hours in a thermos)).

Before you choose

Check the label for the Latin name (Crataegus monogyna), and choose the form that suits your cupboard.

Traditional uses & research +

Botanical taxonomy: Crataegus monogyna (Rosaceae (Rose Family)) · Tradition: Nutritive & Berry Tonics · Key constituents: Oligomeric procyanidins (OPCs), Vitexin, Hyperoside, Rutin.

Curated collections: Ruby Berries & Floral Tisanes · Seasonal Harvest & Winter Apothecary · Seasonal almanac: May Almanac (May Blossom & Early Meadow Florals) · September Almanac (Autumn Equinox Berries & Prairie Cones).

Traditional background: Celebrated in Celtic and British Isles folklore as the 'May Tree', hawthorn hedgerows have bordered pastureland for centuries, yielding both fragrant spring flower tops and autumn berries.

Everyday & kitchen uses: Simmered into rich ruby decoctions, slow-cooked into hawthorn berry jams and solid extracts, or steeped with linden and rosehips.

Standard preparation methods (compare all 50 steeping temperatures):

Simmered Berry Decoction (5 g (1 tbsp whole dried berries) at 205°F–212°F covered simmer): Simmer 15–20 min in 10 oz water (or steep 8 hours in a thermos)
Spring Leaf & Blossom Infusion (2 g (1.5 tbsp dried flowering tops) at 200°F (93°C)): 10–12 min covered
Autumn Hawthorn-Cinnamon Cordial (1/2 cup hawthorn berries + 1/4 cup rosehips + 1 cinnamon quill simmered in 3 cups water at Simmer 25 min, mash & strain): Stir in 1/2 cup raw honey once warm

Cautions & interactions +

General information, not medical advice. Check with a doctor or pharmacist before using this herb if you are pregnant, breastfeeding, giving it to a child, taking medication or managing a health condition.

Who should use caution: Some hawthorn supplements might be safe short term, but no studies have tested use beyond 16 weeks. Side effects can include dizziness, nausea, vomiting, diarrhea and muscle pain. Evidence in heart failure is conflicting, and one study suggested possible early worsening. Interactions with digoxin, beta-blockers and other heart drugs remain mostly theoretical, but one lab study advised avoiding it with digoxin. Safety in pregnancy and breastfeeding has not been established. Chest pain, swollen legs or breathlessness need urgent care. Avoid tejocote root products: FDA found some contained toxic yellow oleander.

Species & lookalike verification: Both One-Seeded Hawthorn (Crataegus monogyna) and Woodland Mid-Style Hawthorn (Crataegus laevigata, syn. C. oxyacantha) are official pharmacopoeial species in Europe and belong to the Rose family (Rosaceae). Identify by its sharp woody thorns (1–2 cm long), deeply lobed toothed leaves, white 5-petaled May blossoms with pink anthers, and crimson autumn 'haws' containing 1 to 2 hard nutlets.

Cupboard storage (amber glass guide): Keep whole dried haws in sealed jars away from pantry moths and humidity.

Which is better to use: Hawthorn Berries or Hawthorn Leaf and Flower?
The European Union herbal monograph covers the spring-harvested Leaf and Flower tops, based on traditional use. Leaves contain the highest levels of oligomeric procyanidins (OPCs) and flowers higher flavonoid levels, whereas the autumn Berries are rich in hyperoside. Many apothecaries combine both in a 'Complete Hawthorn' infusion!

Why do Hawthorn blossoms smell slightly musky in the garden when fresh, yet taste sweet when dried?
Freshly opened white hawthorn blossoms produce trace amounts of trimethylamine to attract pollinating beetles and flies. As soon as the blossoms are gently dried in the shade, that volatile amine dissipates completely, leaving a mild, nutty-sweet floral tea.

Can you eat the hard seed inside a Hawthorn berry?
Like its cousins the apple and cherry (all in the Rosaceae family), the hard inner stone/seed (pyrene) inside a hawthorn berry is rock-hard and is not eaten. You simmer or mash the fleshy red berry pulp and strain out the hard inner stones.

Why is Hawthorn called the 'May Tree' in British folklore?
In England and Ireland, Crataegus monogyna bursts into snow-white bloom at the beginning of May (around Beltane / May Day)—giving rise to the old proverb 'Cast ne'er a clout till May be out' (meaning do not shed your winter coat until the May hawthorn blossom is fully open, not the calendar month of May!).
