Primrose

The poison of the Primrose occurs in its glandular hairs, which break easily and discharge an irritating fluid which is absorbed into the skin.

But skin symptoms of poisoning appear in sensitive patients even without coming in direst contact with the plant, mere nearness being sufficient, just like Poison ivy. Intermittency of symptoms; worse right side. Pain in liver and spleen. Deep infiltration and tension of tissues; blisters. Paralyzed sensation. Weakness. Pharyngeal soreness alternates with diminished facial irritation
