		facts[8]="Peat moss, particularly Sphagnum peat moss from bogs, dressing is more absorbent than cotton and has been used during the World Wars as wound dressing, owing in part to its antibiotic properties.";
		facts[9]="Peat moss, which is primarily harvested from bogs, has been used as an absorbent in feminine hygiene products.";
