Comfrey (Symphytum officinale) is a perennial plant with large, hairy leaves and bell-shaped purple flowers. For centuries, it appeared in traditional remedies and folk medicine, often recommended as a tea. Today, however, modern science and health authorities agree on one critical point:

👉 Comfrey tea should not be consumed as tea or any internal preparation.

Comfrey contains pyrrolizidine alkaloids (PAs) — naturally occurring compounds that can cause severe liver damage, including veno-occlusive disease and liver failure when ingested, even in small or repeated amounts.

Because of this risk, comfrey tea is unsafe and strongly discouraged. Modern guidelines restrict comfrey use to topical, PA-free products, used externally and only for short periods.

Why Comfrey Tea Is Dangerous

1. Liver Toxicity Is Well Documented

Scientific literature and clinical case reports link oral comfrey use to serious liver injury. Pyrrolizidine alkaloids are metabolized in the liver into toxic compounds that can block blood flow and damage liver tissue.

Unlike many herbal teas, there is no safe homemade dose of comfrey tea.

2. Pyrrolizidine Alkaloids Transfer to Infusions

Studies show that PAs can leach into water during brewing. This means that even weak or diluted comfrey tea can be harmful, especially when consumed repeatedly.

3. Regulatory Authorities Prohibit Internal Use

Health agencies in Europe, North America, and other regions advise against ingesting comfrey in any form — including teas, capsules, tinctures, or powders.

What Is Comfrey Used for Today? (Safe Context)

✅ Topical Use Only (PA-Free Products)

Modern medicinal use of comfrey is limited to external applications, such as creams and gels made from specially processed comfrey root that has had pyrrolizidine alkaloids removed.

These products are:

• Labeled PA-free
• Intended for short-term topical use
• Used only by adults
• Not applied to broken skin

⚠️ Never attempt to make homemade comfrey salves, poultices, or oils.

---

Why Old Remedies Are No Longer Recommended

Historically, comfrey leaves and roots were brewed into teas or applied internally before the toxic effects of PAs were fully understood. As scientific methods improved, these risks became clear.

👉 Traditional use does not equal safe use.

If you encounter recipes online promoting comfrey tea, consider them outdated and unsafe.

Nutrition Note (Standard Herbal Infusion Reference)

Herbal teas prepared without sweeteners contain negligible calories and macronutrients, as only small amounts of plant material are used.

⚠️ Reminder: This nutritional reference applies to herbal teas in general — not to comfrey, which must not be consumed.

• Pregnant or breastfeeding individuals
• Children and adolescents
• People with liver disease
• Anyone using multiple topical products simultaneously without guidance

Conclusion

Comfrey is not a safe herbal tea. While it remains valuable as a garden plant and, in regulated form, as a topical ingredient, its internal use is prohibited due to well-established liver risks.
