Horseradish
Armoracia rusticana
Armoracia rusticana, commonly known as horseradish, is a perennial plant native to Western Europe and parts of Asia. Traditionally, it has not been extensively used in any specific medical traditions. Scientific evidence suggests that horseradish may have some potential health benefits; for instance, a combination therapy involving Tropaeolum majus and horseradish showed accelerated healing of bronchitis symptoms after three days compared to placebo. Additionally, horseradish extracts demonstrated significant quorum sensing inhibition activity against Pseudomonas aeruginosa, downregulating virulence genes and showing synergistic effects with antibiotics. The ethyl acetate fraction of Armoracia rusticana's crude ethanolic extract also exhibited high corrosion inhibition efficiency above 96% in 1 mol L-1 HCl, supporting its potential use in functional foods. No major safety issues or recorded drug interactions have been identified for horseradish to date.
