Blood pressure

High blood pressure (hypertension) means the blood pushes too hard against the artery walls over time, raising the risk of heart disease, stroke and kidney problems. It often develops silently over years, shaped by heredity, diet (especially salt), stress, alcohol, excess weight and too little movement, and is called "the silent killer" because you rarely notice anything until it's well advanced.

Plants and herbs that help

Hibiscus (roselle), A US study showed that 3 cups of hibiscus tea daily for 6 weeks lowered both systolic and diastolic blood pressure compared to placebo.
Garlic, A review of 12 studies showed an average drop of 8.3/5.5 mmHg with garlic supplementation.
Beetroot, The nitrate content of beetroot juice has solid scientific documentation for a blood-pressure-lowering effect at doses of around ½ litre of juice.
Celery and parsley, Traditionally used as mild diuretic plants that can ease the circulation.
Hawthorn (Crataegus monogyna), One of the best-documented heart herbs in European herbal medicine, a meta-analysis of randomised, placebo-controlled trials shows a significant lowering of systolic pressure after 2-6 months of use. It works by promoting nitric-oxide-mediated dilation of blood vessels and strengthens the heart muscle's pumping power, so it is regarded as a heart tonic rather than an acute remedy.

Recipes

Tea

Hibiscus tea

Hibiscus is deep red as a ruby and tastes tart like cranberry. It is the most beautiful tea in the apothecary, and also the one with the most convincing research behind it. Several studies show that daily hibiscus over weeks can lower blood pressure measurably. Not dramatically, but enough to count. The key word is daily. One cup does nothing. It is three cups a day for six weeks that shifts something.

Drink

Beetroot-celery juice

Beetroot is one of the few things in the apothecary where the effect can be measured with a blood pressure monitor within a couple of hours. The nitrates convert in the body to nitric oxide, which widens the blood vessels, and pressure falls measurably. It is deep red, earthy and sweeter than you expect. The apple is there to make it drinkable. One thing you should know so you are not alarmed: beetroot turns urine red. It is completely harmless and is called beeturia. But it is an unpleasant surprise on a toilet at seven in the morning if nobody has told you.

Drink

Garlic-lemon-honey tonic

There is one step in this recipe that looks like a mistake, and it is the whole secret: you crush the garlic and let it sit for ten minutes before doing anything else. Allicin, the active compound, does not exist in a whole clove. It only forms when the cell walls break and two substances meet, and that process takes time. Use the garlic immediately and you get the flavour without the effect. Ten minutes. Set a timer. The rest is simple: lemon, honey and water, overnight in the fridge, and a glass in the morning.

Tincture

Hawthorn tincture

Hawthorn is the heart''s plant. Not poetically, but literally: it is one of the best-documented herbs we have for the heart and circulation, used for mild heart failure, palpitations and high blood pressure. I make it twice a year. In spring with the flower heads, when the whole hedgerow stands white and smells heavy. In autumn with the deep red berries. Both work, and you can make them separately or blend them. It must be **common hawthorn**, Crataegus monogyna. You know it because each berry has one stone, not two. And it works slowly. Weeks to months, not days. It is a plant you walk beside, not one you reach for.

Warning

If you are on medication for high blood pressure or heart disease (e.g. digoxin, beta-blockers or other cardiac medicine), always talk to your doctor before adding hibiscus, garlic supplements or especially hawthorn in larger amounts, hawthorn affects the heart's rhythm and force and can amplify the effect of heart medication.
