The "poison" in poison oak (Toxicodendron diversilobum) is a volatile oil called urushiol. If you come in contact with the plant and are sensitive to the oil, you will develop an oozing rash that will itch and burn for two to three weeks. Herbal treatments for poison oak relieve most of the symptoms, including the inflammation, itching and burning. They also prevent infection and promote healing of the broken skin.
Aloe
Aloe (Aloe vera) gel can give immediate relief from the burning and itching of poison oak. It is a cooling substance that will reduce the pain and repair cracked skin. You can apply aloe throughout the healing process so your skin will heal without scarring. Aloe has antibacterial properties to guard against developing an infection in the broken skin, and will also reduce inflammation. Do not take aloe internally if you are pregnant or breastfeeding, since the aloin in aloe can cause uterine contractions.
Oat Straw
Oat straw (Avena sativa) added to your bath can relieve the itching and help restore your skin's smoothness. If you've been scratching the affected areas, your skin may be rough and broken. Along with anti-inflammatory and antibacterial agents, oat straw contains silicic acid. In the 2005 issue of the "Archives of Dermatological Research," scientists reported that a form of silicic acid had a beneficial effect on skin and restored its elasticity and smoothness.
Myrrh
Myrrh (Commiphora molmol) has been used for centuries for its antimicrobial properties. Since one of the dangers of a poison oak rash is infection, the resin in myrrh is useful to guard against different types of bacterial infection. Myrrh is also an astringent and will help dry up the oozing rash. The "Therapeutic Herb Manual" recommends using myrrh tincture externally, either full-strength or diluted with water, depending on your preference.
Goldenseal
Goldenseal (Hydrastis canadensis) reduces inflammation and prevents bacterial infection. Goldenseal is also a potent astringent and, when applied externally, helps dry up any oozing sores or rash. Do not take goldenseal internally if you are pregnant or breastfeeding.
Witch Hazel
Witch hazel (Hamamelis virginiana) contains tannins that can dry up any oozing from the rash without drying out your skin. In his book, "Medical Herbalism: the Science and Practice of Herbal Medicine," herbalist David Hoffmann calls witch hazel a major anti-inflammatory and skin astringent. He recommends applying witch hazel in ointment form.
