What the Science Says
Geranium extract comes from the Pelargonium graveolens plant and contains compounds with antioxidant, anti-inflammatory, and antimicrobial properties. In animal studies, it showed potential to protect kidney cells from oxidative damage caused by acetaminophen overdose. Lab studies also suggest its essential oils and extracts may act as natural preservatives with antimicrobial and antiviral activity. No human clinical trials have been conducted, so how these effects translate to people is unknown.
What It Doesn't Do
Not proven to protect human kidneys. No evidence it detoxifies the body in healthy people. No human trials mean any anti-aging or immune-boosting claims are pure marketing. Don't assume animal study results apply to you.
Evidence-Based Benefits
May reduce kidney damage from acetaminophen toxicity in animal models.
