10. Lemon Juice
Lemon Juice has been used for centuries to provide relief from the sting of insect bites and skin rashes like those caused by poison oak. The natural astringent properties of lemon juice help to relieve the itch and reduce the swelling. You can apply freshly squeezed lemon juice directly to the affected areas and allow it to dry. Keep reapplying until you experience relief. Alternatively, try mixing cornstarch and lemon juice to a fine paste and apply this to the affected skin. Whatever you do, remember not to rub hard as this will only aggravate the skin and increase the itchiness.
