                                According to research on Indian horse chestnut (a related species), the seeds contain a potassium content of 0.79%, indicating it is a significant source of this mineral. In contrast to common sweet chestnuts, horse chestnuts are generally not consumed directly due to the presence of toxins, so their potassium content is not a dietary concern for most people.
