Vitiligo treatment in Ancient Egypt and India and plants used (Procopy Reading #6chapter 9 pages: 49-54)

Vitiligo is a long term skin condition characterized by patches of the skin losing their pigment. The patches of the skin affected become white and usually have sharp margins. The hair from the skin may also become white. The inside of the mouth and nose may also be involved. Often the patches begin on areas of skin that are exposed to the sun. It is more noticeable with dark skin.

Egyptians used the juice or an extract of bishop's flower to treat Vitiligo. Rubbed the juice on the patients patches and then the patients laid the sun. The patches darkened and became less prominent.

Vitiligo can occur in any ethnic population and it is still used today.

The passage below is derived from which one of the following readings described below? A pervasive issue is Walters's use of military metaphors. Although they are inevitable in this context, Walters often over-eggs: the chapter titles, for instance, range from "Call to arms" to"Weapons of war". Such language has shaped the mental constructs of biologists who study"evolutionary arms races". But military metaphors themselves evolve as wars shift from outright destruction to the gain of strategic aims, and the military rarely leads when it comes to understanding interactions. Plant-heterotroph interplay is likely to be nuanced, given how long most of the partners have been at it. Summoning ideas of conflict can limit thinking, as doctors have found in treating disease
