Herbal Remedies for Dermatitis and Hives (Uticaria)

 



Herbal Remedies for Dermatitis and Hives (Uticaria)

Dermatitis encompasses several skin disorders. Any skin inflammation may be considered dermatitis. Substances that irritate the skin, allergic reactions to drugs, detergents, and other chemicals are all culprits. Dermatitis can affect almost any area of the body. Redness, scaling, and thickening of the skin may occur. Pinpointing the cause of the problem is the first step toward alleviating the symptoms.

Dermatitis is not an age specific disorder and can appear on any one and can appear anywhere on the body, although as mentioned above, it is most often seen on legs, feet, arms and ears. There are often predispositions to this disorder. It is seen in heredity and can be traced through family history.

Dermatitis is divided into different classifications. Acute and chronic dermatitis are differentiated by a time period as well as symptoms. Acute dermatitis is seen with erythema and edema in papules, vesicles and sometimes large blisters. Chronic dermatitis is seen as lichenification, scaling and fissures. There is a thickening of the dermal layer. Contact dermatitis is another classification, which is skin irritation due to exogenous agents such as water and other fluids, abrasives such as cleaning products, chemicals such as acids and alkalis as well as solvents and detergents.

Urticaria, or hives, is the most frequently appearing dermatologic disorder in the clinic. It appears as raised, circumscribed areas of erythema and edema involving the dermis and epidermis that are very pruritic. Uticaria is an allergic reaction limited to the skin. It often results from: an allergy to certain foods; medications; insect stings or bites. Hives may appear as a symptom of some viral infections such as hepatitis, measles, and mononucleosis. Parasitic infections are common causes of urticaria in tropical climates. Non-infectious diseases are sometimes associated with urticaria, including lupus erythematosus, and hyper- and hypothyroidism. Some women develop urticaria during menstruation. Psychological factors may play a role in the etiology of chronic urticaria.

There is different etiology. One is allergic response from the interaction of antigen and antibody. Most urticaria especially acute urticaria is due to immune response. Second kind is due to histamine release. The third is factors cause blood vessel dilation. Fourth etiology is from irritation of blood vessel and inheritance. Allergic reaction is the most common reason for urticaria. Some biological, chemical and physiological factor can directly stimulate the release of histamine. Emotional stimuli, exercise can stimulate the release of histamine also. Urticaria can also be caused by lack of certain digestive enzymes. Some drugs, emotion, drinking alcohol can induce urticaria in sensitive people due to blood vessel dilation.

Urticaria may be acute (lasting less than 6 wk) or chronic (lasting more than 6 wk). Pathophysiology Urticaria results from the release of histamine, bradykinin, leukotriene C4, prostaglandin D2, and other vasoactive substances from mast cells and basophils in the dermis.

These substances cause extravasation of fluid into the dermis, leading to the urticarial lesion. The intense pruritus of urticaria is a result of histamine released into the dermis. Histamine is the ligand for 2 membrane-bound receptors, the H1 and H2 receptors that are present on many cell types. The activation of the H1 histamine receptors on endothelial and smooth muscle cells leads to increased capillary permeability. The activation of the H2 histamine receptors leads to arteriolar and venule vasodilation. This process is caused by several mechanisms. The type I allergic IgE response is initiated by 26 antigen-mediated IgE immune complexes that bind and cross-link Fc receptors on the surface of mast cells and basophils, thus causing degranulation with histamine release.

Causes include: Food, drugs, infection, insect bite, emotion, physical stimulation can all cause urticaria.

1. Food: Food is often the major causative factor in acute urticaria. Such as seafood, shell fish, chicken, eggs, tomato, strawberry, garlic.

2. Drugs: such as vaccine, aspirin, and insulin.

3. Inhaled particles: pollen, dust, and animal dander.

4. Infection: Bacterial infection such as tonsillitis, sinusitis, UTI, upper respiratory tract infection, prostitis, hepatitis, and parasite ovum.

5. Insect bite: insect sting often causes urticaria. Mite, tic often cause urticaria papulosa.

6. Physical factor: Cold, heat, sunshine, friction and pressure can cause immune or non-immune urticaria.

7. Hereditary: Urticaria patient often has family history of allergies.

Herbal Remedies for Dermatitis

Herbs that are beneficial for dermatitis (if you are not allergic to them) include burdock root, chamomile, cedarwood, dandelion, marigold, red clover, thyme, and verbena.

A study published in the British Medical Journal Lancet showed a significant improvement in eczema when patients took high doses of Evening Primrose Oil (EPO) in capsule form. There have been some reports that EPO can help in cases of atopic dermatitis. It takes a rather large number of these expensive capsules to produce results and it can take at least six months to see any results.

Flaxseed oil taken internally or applied externally often eases symptoms of eczema.

Aloe vera gel and Calendula lotion or cream can sooth irritated skin.

Take 500 milligrams of Black Currant Oil twice a day. Give children under 12 half that dose. This takes six to eight weeks to produce the desired effect.

Burdock Root - Helps to purify blood and restore the liver to aid in a restful sleep. Helps to reduce build up of toxins in the skin resulting in boils and other skin disorders. Helps gallbladder functions and stimulates the immune system.

Chamomile - Chamomile's medicinal properties range from skin inflammations to lightening hair to treating digestive problems. As a mild sedative, anti-inflammatory, and antibacterial, it improves digestion by relaxing the muscles throughout the gastrointestinal system and it can induce an overall sense of calm and well-being.

Dandelion - is a leading remedy for detoxing the liver. It stimulates the flow of bile, a fluid that aids fat digestion, which is why it's used for liver and gallbladder disorders. Dandelion has scientifically documented potent diuretic properties. It relieves constipation and eases bloating and swelling. Dandelion should be used for 4 to 6 weeks at a time. For it's liver benefits dandelion is helpful for skin disorders.

Red Clover - is an herb suggested for chronic conditions affecting the skin. It is a diuretic, but it's unknown exactly how it works for skin conditions. Use nonfermented red clover which is safe. Red clover contains a substance called genistein, which has anticancer properties.

Thyme Leaf - The pungent oils found in Thyme are an effective anti microbial in the treatment of respiratory infections. When taking Thyme, people often note tasting it on their breath as the oils permeate through the respiratory system to reduce the proliferation of viruses during infections. It also warms the digestion and reduces metabolic congestion, aiding to clear the body of conditions for infection.

Aloe vera looks like a cactus with soft leaves. The fluid contained in the leaves has been used for centuries to treat burns and minor wounds. Today, aloe gel is used frequently as an ingredient in cosmetics, creams, ointments and suntan lotions. A study published in 1996 in Tropical Medicine and International Health found that aloe vera was very effective in the treatment of psoriasis. By the end of the 16-week study, a cream with aloe vera extract caused a significant clearing of psoriasis in 25 of 30 patients, compared to two out of 30 with the placebo. However, a study published in May 2005 in the Journal of the European Academy of Dermatology and Venereology found that the effect of commercial aloe vera gel on stable plaque psoriasis was modest and not much better than placebo.

Apple cider vinegar and many different types of vinegar (derived from dates, figs, etc.) have been used by many ancient cultures for medicinal purposes. Apple cider vinegar has been used throughout the years as a disinfectant or soothing agent. The Psoriasis Foundation hears from people who apply apple cider vinegar to their skin as a treatment for psoriasis. People add it to the bath, mix it with a moisturizer, soak fingernails and toenails in it, and apply it directly to the skin with cotton balls or pads.

Capsaicin, a natural ingredient found in cayenne peppers, has been shown in some studies to work on redness, scaling and itching of the skin. Researchers have shown that capsaicin interrupts the action of substance P, (a molecule which affects how the brain recognizes pain and itch sensations) at the nerve ending. In two separate studies with psoriasis patients, 0.025% capsaicin cream used topically was effective in decreasing scaling and redness. The main side effect was a short-lived burning sensation. Several studies indicate that topical capsaicin products can also help reduce joint pain associated with psoriatic arthritis. Capsaicin can cause a severe burning sensation if it comes in contact with the eyes, nasal passages or mucous membranes.

Emu oil is reported to be helpful for dermatitis suffers of all kinds, as this oil has a protective and softening effect on the skin. The exact mechanism by which emu oil works is not known.

Oats and oat extracts have been used for centuries as soothing topical agents. Oat plant derivatives have been used to manage dry, itchy skin conditions. Many bath products include colloidal oatmeal as the active ingredient. You can make your own oatmeal bath. Combine one cup oats, one quarter cup dried milk and two tablespoons apricot kernel oil. Pulverize the oats and dry milk in a food processor or blender. Gradually mix in the oil. Place the mixture in a cotton bag, sock or handkerchief and put in the tub while filling. To release the preparation, squeeze while soaking in the bath.
