Raspberry leaf

Rubus idaeus

Leaf · cooling · astringent

A mineral, tightening leaf — sour air for a heavy cycle or a loose bowel.

In the mouth

How it tastes

Black-tea astringent, green, faintly fruity.

Traditional use

Sour and tightening. Kitchens used raspberry leaf for a heavy cycle, a loose bowel, and as a late-pregnancy tea in the oral tradition. It is astringent air: it draws tissues together.

In the cup

1 tbsp dried leaf in a pint, steeped 15 minutes or long-infused. Pleasant, tea-like, easy to drink.

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.

Some people, or a long pot, need extra care.

Culinary-tea amounts are the tradition. Pregnancy use is folk custom, not a standing order — ask the person who is actually catching the baby.
