Hibiscus

Hibiscus sabdariffa

Calyx · cooling · lifting

A crimson sour that drinks like a summer cooler and a winter tonic.

In the mouth

How it tastes

Brightly tart, cranberry, floral, refreshing. A deep red cup. Can be quite acidic.

Traditional use

Agua de jamaica and karkadé are kitchen drinks first. Folk use treated hibiscus as a cooling, circulating sour for hot days, flushed states, and a palate that needed brightness.

In the cup

1 tbsp dried calyces, steeped 8–10 minutes or simmered briefly. Excellent iced with a little sweet. Stains badly.

Blood

Sour blood · sour

Sour is cooling and astringent. It draws and binds, thickens thin blood, starts saliva, and hydrates even as it tightens. Sour plants carry the antioxidants of fruit. They move mucous and support the lungs — large doses irritate. Lemon-family plants show up again and again in sinus cups.

The promise

A careful hand

Ordinary tea for a healthy adult.

May modestly lower blood pressure — watch if you already take that kind of medicine. High acid can bother a tender stomach or enamel if you sip it all day. Food amounts in pregnancy; some hands say moderation.
