Scabies, usually called the 7 year itch, is a sort of skin infection that is contagious when direct skin contact happens. This type of infection is caused by a parasitic mite, referred to as Sarcoptes Scabiei, that digs under the skin and causes an allergic reaction and itching. Scabies treatments include home remedies and prescriptions such as Permethrin, Ivermectin and Crotamiton. While Lindane was at one time very popular to combat them, this is no longer the case because of developed resistance. Actually, there are several scabies home remedies to consider. One of the best choices is tea tree oil, which stops the itching and helps heal skin rashes. Tea tree oil is also known to kill the mites including their eggs so there will be no chances of you becoming infected with scabies again.
