Comes from a plant so it's reasonable that you could be. I found this info regarding peppermint:
Symptoms of contact sensitivity and ulceration from oral menthol/peppermint-containing products improved with discontinuation and avoidance of these products. 61
Following ingestion of 40 drops of peppermint oil, a patient with no known allergies reported mucosal burns and edema of the tongue and oral cavity. 52 Excessive consumption of mint-flavored sweets caused stomatitis with oral papillary hypertrophy.
Avoiding it might be wise.
Be well, Sandi
