Coal tar is a thick, black liquid made from coal. It is used in a variety of medical treatments, including psoriasis, eczema, and seborrheic dermatitis. When applied to the skin, it helps reduce itching, scaling, and inflammation. It also helps to soften the skin. Coal tar has been used as a medical treatment for centuries and is available over the counter in a variety of forms, including creams, ointments, and shampoos.
Coal tar is a thick, dark liquid byproduct of the coal gasification or coking process. It has both medicinal and industrial uses.
Medicinally, coal tar is used as a topical treatment for:
- Psoriasis: A chronic autoimmune skin condition that causes itchy, scaly patches on the skin.
- Seborrheic dermatitis (dandruff): A common scalp condition causing flaking, redness, and itching.
- Eczema: A group of inflammatory skin conditions that cause itchy, red, and inflamed skin.
- Lice: Coal tar shampoo can help kill head lice and their eggs.
How it works:
The exact mechanism of action of coal tar for these conditions is not fully understood. However, it is believed to have several potential effects:
- Reduces inflammation and itching: Coal tar may help to reduce the activity of certain immune cells involved in inflammation, thereby reducing itching and discomfort.
- Slows down skin cell growth: In conditions like psoriasis, skin cells grow too quickly. Coal tar may help to slow down this process and normalize the appearance of the skin.
- Antifungal and antibacterial properties: Coal tar may also have some antifungal and antibacterial properties, which may be beneficial in certain skin conditions.
Important considerations:
- Over-the-counter (OTC) availability: Coal tar is available in various over-the-counter (OTC) products, including shampoos, creams, and ointments.
- Follow instructions carefully: It is crucial to follow the instructions on the product label carefully and not use coal tar for longer than recommended as it can cause irritation and other side effects.
- Potential side effects: Coal tar can cause side effects such as skin irritation, burning, and sensitivity to sunlight.
- Not for everyone: Coal tar is not suitable for everyone and should not be used by pregnant or breastfeeding women or individuals with certain medical conditions.
Consult a healthcare professional:
- Before using coal tar, especially if you have any underlying health conditions or are taking other medications.
- If you experience any severe or persistent side effects while using coal tar products.
Remember: Coal tar should only be used under the guidance of a healthcare professional for specific skin conditions. It is not a cure for any condition and does not address the underlying cause.
