- Chinese

- Pinyin
- Tong Lv
- Latin
- Aerugo
Known in TCM as Tong Lv (铜绿), this sour and astringent, neutral herb enters the Liver and Gallbladder. Traditionally, it historically removed toxicity and astringed ulcerated tissue ... Tong Lv was used externally on chronic sores, erosive lesions, and difficult nonhealing surfaces, most often applied for abscess, pharyngitis, and tonsillitis. Modern research has identified Copper among its active constituents.

Traditional Use
Primary Actions
- Historically removed toxicity and astringed ulcerated tissue ... Tong Lv was used externally on chronic sores, erosive lesions, and difficult nonhealing surfaces.
- Historically reduced throat swelling and phlegm in highly restricted internal traditions ... a lane that is much less acceptable now because of copper toxicity.
- Historically dried corrosive damp lesions and helped remove necrotic material ... mainly in topical or procedural contexts.
Secondary Actions
- This is a mineral record with significant toxicity and should be read as documentary and safety-first, not as routine modern herbal guidance.
- Modern literature is far stronger on copper toxicology than on validated therapeutic use of Tong Lv itself.
Classic Formulas
- Historical topical powders and washes for ulcerated sores and toxic lesions ... the most defensible traditional lane to preserve.
- Historical throat-swelling or phlegm-dispelling formulas ... documentary only and not appropriate for casual revival.
- Surgical-style external use traditions for proud flesh and difficult wound surfaces ... an old materia medica context rather than a modern home-remedy one.
Classical References
- Traditional summaries describe Tong Lv as sour, astringent, neutral, and toxic, entering the Liver and Gallbladder to remove toxicity, astringe sores, and transform pathological accumulation.
- Even older texts treat it as a potent material requiring care, which aligns with the modern safety-first interpretation.
Modern Research
Active Compounds
- Copper acetate and related verdigris-type copper salts
- Corrosive copper-ion fractions responsible for both historic topical action and modern toxicity concerns
- Heavy-metal exposure risk rather than validated herbal-style bioactivity
Studied Effects
- Indexed modern literature specific to Tong Lv or Aerugo as a medicine is sparse, and contemporary relevance centers far more on copper toxicity than on therapeutic validation.
- For that reason, this page should be read mainly as a historical specimen record with strong modern caution rather than as an evidence-backed current-use mineral monograph.
Safety & Interactions
Contraindications
- Pregnancy
- Kidney or liver vulnerability
- Any unsupervised internal use
Cautions
- Verdigris is a toxic copper material and should not be treated like an ordinary botanical or food-derived remedy.
- Historical internal use is difficult to justify under modern safety standards, and topical use still requires substantial caution.
