About Loyd

Loyd is a major Polish tea brand, well distributed across Eastern Europe, increasingly available in UK specialty importers and Polish/Eastern European food shops. The range covers black tea, green tea, fruit infusions, and a functional herbal range that includes Loyd Boost Immunity, "Digestion Support," and "Good Night's Sleep."

Loyd's functional teas are affordable products, priced like the UK's Pukka or Twinings herbal ranges, with distinctly Polish and Eastern European herbal traditions in the recipes.

What's in Boost Immunity

Elderberry / elderflower. Traditional cold support herb.
Echinacea. A traditional cold season herb (mixed clinical evidence).
Ginger. warming, anti nausea.
Lemon balm. Mildly soothing.
Citrus (lemon, orange peel). Brightness, traces of vitamin C.
Possibly: rosehip, hibiscus, other supporting herbs.

What it tastes like

Bright, fruity tart, with elderberry depth and ginger warmth. The cup is golden amber with a fresh aromatic. More approachable than pure echinacea (which can be earthy bitter). Honey complements; lemon optional.

The "boost immunity" framing, under scrutiny

Don't expect dramatic effects:

Echinacea: Mixed evidence for modest cold duration reduction when started at first symptoms. More on echinacea.
Elderberry / elderflower: A traditional cold season choice; some weak clinical evidence.
Ginger: warming; a modest comfort when ill.
Combined: Pleasant warming herbal blend with gentle supportive properties; not a vaccine substitute.

The tea is a useful warm refreshing cup during cold season. Don't rely on it to fight off illness.

How to brew

1 bag per 200ml.
Just boiled water.
Steep 5-7 minutes.
Sweeten with honey to taste.
Add lemon for brightness.

Use cases

First signs of cold onset. Where echinacea evidence is strongest.
Cold and flu symptom support. Warming hydration helps regardless.
Caffeine free evening drinking during illness.
Children (older). For children, ask a GP, pharmacist or health visitor about Loyd ages and doses; we don't advise on them. Check echinacea labelling for age recommendations.

Cautions

Conditions where the body attacks its own tissue. Echinacea may interact theoretically; discuss with GP.
Pregnancy. Limited research on echinacea in pregnancy; some sources advise short term use only at cold onset rather than daily preventative.
Allergies. Echinacea is in the Asteraceae family, possible cross reactions.
Children under 12. Some echinacea products advise against; check label.
