Transformational Gardening

Disclaimer: Foraging can be fun, rewarding and provide health benefits. As a novice forager, I will be sharing my foraging experiences. However, in order to be safe, always consult with local foraging experts and guidebooks before beginning foraging. Children should learn to forage safely by being guided by experienced adults. Never ingest anything unless you are certain of the identification and safety of the plant. Some plant species are inedible and some are poisonous.

Food & Medicinal Uses

Contraindications: Because sorrel has oxalic acid (like spinach and beet greens) it is important not to use it excessively as calcium uptake from meals will be lower when oxalic acid is ingested. Persons with kidney stones, gout or rheumatism should be conscious of ingesting in moderation. Selection of traditional/historical food, medicinal and other uses gathered from references listed below. Please read referenced books below for complete information.
