Supplements with too much Vitamin A can be toxic to the liver since Vitamin A is a fat soluble vitamin (meaning more gets stored than excreted.) Sweet potatoes and other foods rich in Vitamin A, however, do not cause liver toxicity and can not be stored for long-term use like supplements can.
The wound healing stages are made up of three basic phases: inflammation, proliferation and maturation. There are many types of wounds that require different wound care products for proper recovery from an ulcer or laceration, but most go through similar healing stages.
SUPERFICIAL BURNS. When you sustain superficial burns, the skin has the capacity to heal. In superficial burns, only the top layer of the skin is damaged. Cells from the hair roots and sweat skin glands will move to the surface of the burn and will build a new surface layer of the skin. The burn will heal in about 7 to 14 days. PARTIAL DEEP BURNS. The superficial and part of second layer of skin are damaged in partial deep burns and the skin might struggle to heal on its own. Cells from hair roots will be the only ones to contribute to skin healing because most of the skin glands were damaged.
