Corallium rubrum. One of the best medicines for whooping cough. The indications for it are as follows: the attacks are so close to each other that they seem to follow each other without interruption; the fits are so violent that the child suffocates, becomes purple and black. Suffocation before the attack and great prostration after it. There is often aggravation in the morning.
Coccus cacti. Violent cough with gagging and profuse expectoration of thick, tenacious, protein-like mucus. This expectoration is more likely in the evening, and during the day the cough is usually dry.
Hydrocyanic acidum. This remedy is most similar to cuprum: during the attack the child becomes stiff and unconscious, intense coloration of the face, cyanosis of the lips and circumference of the mouth; the attack is relieved by a few sips of cold water.
Squilla has the opposite characteristic; if the child drinks any amount of cold water, a violent fit immediately sets in. During the day the cough is mild, but every night from 11 p.m. to 3 a.m. suddenly begins a very painful suffocation; the child rises on tiptoe, leans back, as if about to suffocate; gradually breathing is restored with a whistle when inhaling; the second attack is milder than the first, and the rest of the night passes fairly well.
Pertussinum – Prepared from mucilaginous sputum that contains the whooping cough virus. Pertussinum should be consumed at the onset of the disease and may be even earlier, during the dubious period of an ordinary cough. During an attack, the child stiffens and loses consciousness, sharp coloring of the face, cyanosis of the lips and circumference of the mouth; the attack is relieved by a few sips of cold water.
