Sarahs mum could have told me this.

Do horses enjoy eating horseradish?

Horses do not enjoy eating horseradish, and they should not eat it. The plant is toxic to horses because it contains compounds that convert into harsh mustard oils upon digestion, and its strong smell and spicy taste naturally deter animals from eating it.

Why Horses Avoid Horseradish

Toxicity: The root contains glucosinolates and sinigrin, which turn into poisonous mustard oils when digested, making horses severely ill.

Natural Defense: The pungent, spicy chemical compounds act as a built-in defense mechanism that repels herbivores.

Instinct: Horses naturally avoid the plant and will not willingly graze on it.

Where the Name Comes From

Coarse or Strong: The prefix “horse” was used historically in English to mean large, coarse, or strong, describing a plant much larger and stronger than a standard garden radish.

Not for Equines: The name reflects the intense flavor of the root, not a preferred snack for horses.
