Recently, news of a 1-year-old baby falling critically ill after accidentally ingesting Zi Cao Oil (Lithospermum oil)—with chest imaging showing completely ‘white lungs’—has sparked widespread concern. Zi Cao Oil is a traditional Chinese herbal topical remedy commonly used for eczema, diaper rash, or minor burns. Its main ingredients include Lithospermum root and olive oil, known for anti-inflammatory and wound-healing properties. However, Lithospermum contains pyrrolizidine alkaloids (PAs), which are hepatotoxic and potentially carcinogenic when ingested.Medical experts warn that infants have immature liver metabolism, making them extremely vulnerable to acute liver injury, pulmonary edema, or even multi-organ failure if they ingest PA-containing products like Zi Cao Oil. The term ‘completely white lungs’ seen on imaging typically indicates severe pulmonary edema or acute respiratory distress syndrome (ARDS), signaling a life-threatening condition.Health authorities stress: Zi Cao Oil is strictly for external use only and must never be ingested—especially by children. Parents should store such products securely out of children’s reach. In case of accidental ingestion, seek emergency medical care immediately and bring the product packaging to help clinicians identify toxic components quickly. China’s National Medical Products Administration has already restricted the use of Lithospermum-containing products, urging the public to exercise caution regarding the safety of traditional topical remedies.
近日，一则‘1岁宝宝误食紫草油后病危，肺部影像全白’的新闻引发广泛关注。紫草油是一种传统中药外用药，常用于缓解湿疹、尿布疹或轻微烫伤，其主要成分包括紫草、橄榄油等，具有抗炎、促进伤口愈合的作用。然而，紫草含有吡咯里西啶类生物碱（PAs），这类物质具有肝毒性和潜在致癌性，口服可能对婴幼儿造成严重伤害。医生指出，婴幼儿肝脏代谢功能尚未发育完全，一旦误服含PAs成分的紫草油，极易引发急性肝损伤、肺水肿甚至多器官衰竭。新闻中提到的‘肺已全白’，在医学影像上通常意味着严重肺水肿或急性呼吸窘迫综合征（ARDS），是病情危重的表现。专家强调：紫草油仅限外用，绝不可内服，尤其要远离儿童。家长应将此类药物妥善存放，避免孩子接触。若发生误食，应立即送医，并携带药品包装以便医生快速判断成分。目前国家药监局已明确限制含紫草成分产品的使用范围，提醒公众谨慎对待传统外用药的安全风险。
