How to take Cramp Bark

These are the everyday prep instructions for Cramp Bark — covered once here so each use case below can focus on what's specific to that purpose.

Decoction
Simmer 1 tablespoon of the dried root or bark in 2 cups of water for 20–30 minutes (lid mostly on). Strain and sip. Decoctions are for hard plant parts that won't give up their actives to a quick steep.
Tincture
Take 30–60 drops in a small glass of water 1–3 times a day. Tinctures are alcohol or glycerin extracts — fast-absorbing, convenient for daily use and travel.
Capsule
Swallow 1–2 capsules (typically 300–600 mg) with water, 1–2 times a day. The easiest form if you don't like the taste.
Dosage

Decoction: 1-2 tsp dried bark in 8oz simmered 15 min, 2-3x daily during cramps; Tincture: 30-60 drops every 2-3 hrs during cramps
