Horseradish (Armoracia rusticana) has a long history of use in traditional medicine, particularly in European folk remedies. It is often cited as a digestive stimulant, believed to promote appetite and aid in digestion. The pungent compounds in horseradish, mainly allyl isothiocyanate, are thought to increase the secretion of gastric juices, which could theoretically enhance appetite. Historical texts and herbal compendia, such as those from the 16th and 17th centuries, note its use as a condiment to stimulate eating and to alleviate symptoms of indigestion or sluggish appetite.

However, scientific evidence directly supporting horseradish for the treatment of excessive appetite is limited. Most modern research has focused on its antimicrobial and anti-inflammatory properties, rather than its effects on appetite regulation. There are a few references in ethnobotanical literature and older pharmacopeias that suggest horseradish can "normalize" digestive activity, which may be interpreted as beneficial for both low and, in some cases, excessive appetite, but these claims are not substantiated by clinical trials.

In summary, the use of horseradish to support or treat appetite—whether low or excessive—is primarily justified by traditional use rather than strong scientific validation. Evidence for its effectiveness in this specific context should be regarded as anecdotal and historical rather than established by rigorous research.
