Blackberry leaf

Rubus allegheniensis

Leaf; ripe berry as food · cooling · astringent

A sour, tightening leaf for a loose bowel and a raw mouth.

In the mouth

How it tastes

Astringent black-tea, green, a berry-leaf finish.

Traditional use

The cane that feeds you in July also makes a drawing tea. Folk cups used the leaf when tissue was too relaxed — bowel, throat, a heavy cycle.

In the cup

1 tbsp dried leaf, steeped 10–15 minutes. Pleasant, tea-like, a little tannic. Ripe berries are food.

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.

Astringent — stop if the bowel binds. Young spring leaf is gentler than old cane leaf.
