Vesp. is the hornet’s signature in human tissues: sudden oedema, wheals, and shining erysipeloid heat with burning–stinging pains that abhor warmth and touch and cease under cold. The portrait expands where mucosae behave like skin: a pendulous, oedematous uvula, glottic narrowing, and throat burning that insists on cold sips; and where renal/vesical mucosa protests with burning urine, frequency, and even albumin/blood after toxic exposure. The right side of face and eye is a recurrent stage for the swelling. The modus operandi is the same from face to fauces to bladder: heat and friction worsen, cold and non-pressure cooling soothe; scratching spreads, gentle cooling contracts. The remedy stands at a three-way junction: with Apis in oedema (yet more throat/urinary and often thirst for cold), with Urtica in urticaria (yet more oedema and laryngeal stake), and with Cantharis in vesical burning (yet craving cold and lacking the constant unbearable urging). Clinically, do the simple things that prove the prescription: strip heat from the patient, air and cool the room, forbid rubbing and pressure, use cold sips and compresses, and choose linen over wool. When this regimen aligns with Vesp., improvement is often swift: the face deflates, the uvula rises, the itch relents without suppression, urine stops scalding, and the patient’s anxiety dissolves with the heat.
