Onion (Allium cepa) has been used in various traditional medicine systems for its purported health benefits, including as a remedy for "blood poisoning," a term historically used to describe conditions like sepsis or systemic infections. In folk medicine, onions were sometimes applied topically or ingested in the belief that their antimicrobial properties could "draw out" toxins or infection from the body. These practices were based on anecdotal observations and passed down through generations, rather than on systematic scientific study.

While onions do contain compounds with antimicrobial and anti-inflammatory properties, such as quercetin and sulfur-containing molecules, there is no robust clinical evidence supporting their effectiveness in treating or supporting recovery from sepsis or blood poisoning. Modern medicine treats sepsis as a life-threatening emergency that requires prompt administration of antibiotics and supportive care. The historical use of onions for this purpose is not recognized or recommended in contemporary medical practice, and relying on onion as a sole or primary treatment for blood poisoning is dangerous.

In summary, the use of onion for blood poisoning is primarily rooted in traditional practices with minimal scientific validation. The evidence supporting its effectiveness is extremely limited, and it should not be used as a substitute for proven medical therapies in cases of sepsis or serious infection.
