Severe dermatitis due to contact with plants, light

My father returned home for a few months. When he came to the garden to irrigate his skin he was blistered, red, itchy, burning sensation. What is my father's illness?

As described in the letter, your father may have dermatitis due to contact with plants, light. This is a light-skinned dermatitis caused by patients exposed to light-sensitive plants (plants) that combine ultraviolet rays with long wavelengths (UVA 320-380m). This is due to the fact that these plants contain a light-sensitive substance (which promotes the body's absorption of ultraviolet radiation) that develops the disease. Symptoms usually appear after direct contact with the plant and begin 24 hours after exposure, peak within 48-72 hours, which are: blistering, redness, dermatitis, itching, sensation burns, increased pain, skin scab (after blisters break). Most damage occurs in open areas (usually the hands, arms, legs, or face) or anywhere, where exposure and exposure to sunlight.

As a precaution, contact with the pathogen should be avoided (avoid pathogenic plants and avoid exposure to light). Avoid other skin irritants (while limiting the use of perfumes). Reduced exposure to sunlight, especially when the UV light is at its highest (10-15 hours daily), can help prevent hyperpigmentation. Always use sunscreen when out.
