In places where the light is stronger there is a photosensitivity reaction to it.
I also found this in a book on poisonous plants>New Zealand workers have noticed that affected sheep whilst in an active stage of photosensitization due to the plant, react violently to contact with cold water. As soon as their forefeet enter the water, they rear on their hind legs and make convulsive movements. A light knock on the head or ear will trigger off similar convulsive movements.
