Boneset. Bruisewort. Healing Herb. For over 2,000 years, Comfrey (\u003cem\u003eSymphytum officinale\u003c\/em\u003e) has been the herb that healers reached for when something needed to come back together. Modern clinical research has validated what herbalists always knew: comfrey’s allantoin content makes it one of the most effective topical healing plants on earth. In the garden, it is simply without equal — a deep-rooted, fast-growing, nutrient-mining powerhouse that permaculture practitioners prize above almost any other plant.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e⚠️ Safety Note:\u003c\/strong\u003e Comfrey contains pyrrolizidine alkaloids (PAs) associated with liver toxicity with prolonged internal use. \u003cstrong\u003eInternal use is not recommended and is restricted or banned in several countries.\u003c\/strong\u003e Topical (external) use is considered safe and supported by European clinical trials.
