Postlethwaite tinctures are made from certified organic herbs, when available,or from wild-crafted sources. Most are obtained from fresh herbs grown in the UK - mainly on their own herb farm in Herefordshire. Postlethwaite's specialise in high-strength tinctures - generally this is the maximum strength achievable whilst still covering the chopped herb with alcohol.
Being more concentrated, these are ideally suited to use in low-volume dropper bottles. Certified Organic by the Soil Association and presented in glass bottles for recycling
