Salt … Safety & Interactions

Shi Yan · Natrii Chloridum

Contraindications

  • Severe edema, uncontrolled hypertension, or states requiring strict sodium restriction
  • Kidney failure or severe fluid-retention disorders
  • Unsupervised self-induced vomiting

Cautions

  • Medicinal Shi Yan is not a license for unrestricted dietary salt use, and excessive sodium intake can aggravate hypertension, renal disease, and swelling.
  • The classic emetic use is the riskiest part of this record and should be treated as historical clinician-guided practice, not as home first aid.
  • Topical saline-style use is generally far safer than internal high-dose use.
