The best way to use it is to apply the oil to the affected areas of the scalp, cover it and leave it to soak overnight. The next morning, it will be easy to comb the flaky skin off. Apply more oil to soothe the skin. Usually, only a few applications are needed.
Other key plants for cradle cap:
Calendula (Calendula officinalis): a well-researched healing herb for the skin with antiseptic, wound healing, anti-inflammatory and pain relieving properties. It is clinically proven for promoting the healing of open skin, cuts and grazes, with beneficial anti-inflammatory and soothing actions in eczema, psoriasis and wounds. It has anti-yeast actions, making it particularly useful in persistent cradle crap.
Chickweed (Stellaria media): This cooling plant is excellent at relieving itching and irritation. It is anti-inflammatory and can speed the healing of grazes, cuts and wounds.
Nettle (Urtica dioica): The leaves of the stinging nettle plant are a traditional first aid remedy to relieve itchiness. Nettle helps to cleanse tissue of inflammatory by-products, reduces swelling and assists in wound healing. It is both anti-allergic and depurative (improves detoxification and waste removal). With a high nutrient content including calcium, magnesium, iron, and vitamins A & C, it provides important nutrients to restore irritated skin.
I recommend the topical application of these plants in a natural, paraben and paraffin free cream base, three to four times daily, until the condition is resolved.
More severe cases of cradle cap will require internal treatment. The focus should be clearing the skin from within, with the use of plants that support the body's natural elimination processes via the liver and the kidneys. Dandelion (Taraxacum officinale), St Mary's Thistle (Silybum marianum) and Heartsease (Viola tricolor) can all be safely used in children as long as the dose is age-appropriate. Seek professional advice in this case.
Additionally, the use of an eczema-specific probiotic strain (e.g. Lactobacillus Rhamnosus GG) may be helpful in restoring and protecting the child's microflora, which are known to play a role in modulating the immune system and reducing the risk of atopic disease. Probiotics administered to breastfeeding mothers significantly reduced the child's risk of eczema and dermatitis during the first two years of life.
If the condition worsens or does not improve, see your leading healthcare professional immediately.
