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.
Ingredients
- 2 tbsp dried hibiscus flowers
- 250 ml boiling water
Equipment
- Strainer
- Jug or cup
- Carafe if drinking it cold
Method
- 1
Pour 250 ml boiling water over 2 tbsp dried hibiscus flowers.
- 2
Steep 5-10 minutes, strain, and drink lukewarm or cold, ideally 2-3 cups daily over several weeks to feel the effect.
Dosage
2-3 cups daily for at least 6 weeks.
Steep 5-10 minutes, strain, and drink lukewarm or cold. It is excellent chilled with ice.
Shelf life
Dried flowers keep 1-2 years, dark and airtight. Chilled tea keeps 2 days refrigerated.
Safety
Hibiscus lowers blood pressure. If you already take blood pressure medication, the two together can lower it too far. Speak with your doctor, and measure along the way.
If your blood pressure is already low, leave this one be.
Not during pregnancy. Hibiscus has traditionally been used to bring on menstruation.
It can affect absorption of certain medicines, paracetamol and antimalarials among them. Keep an hour between it and your tablets.
The acidity can wear at tooth enamel over time. Drink it through a straw if you drink it daily, and rinse with water afterwards.
High blood pressure must be measured and followed by a doctor. This tea is a supplement, not a replacement for treatment, and you must never stop your medication on your own.
How the herbs work
Hibiscus contains anthocyanins, the same pigments that make the flower red, and they widen the blood vessels. Blood meets less resistance, and pressure falls.
It is also mildly diuretic, which contributes to the same effect.
The effect is documented in several controlled trials, but it is gradual. It builds over weeks and fades again if you stop.
