Meadow grass/Kentucky blue is native to Europe and Asia, this grass now has worldwide distribution in temperate regions. It is probably the most important introduced grass in North America. It is best adapted for growth in cool, humid climates. In North America, though it occurs in every one of the United States, it is most prevalent in the northern half of the United States and the southern half of Canada. It is a highly palatable pasture grass and is also extensively used for lawns and turf. It is a major pollen-producer. Meadow grass pollen is a common inducer of asthma, allergic rhinitis and allergic conjunctivitis. The symptoms of phytophotodermatitis usually begin 24 hours after exposure and peak between 48-72 hours. Symptoms can be mild or severe and include: large areas of blistering, itching, redness, inflammation, pain, tenderness, burning sensation , crusted patches of skin (once blisters burst). The patches of blisters are usually irregularly shaped. The patterns represent the areas of the skin that were exposed to the chemical. For example, blisters in the pattern of drips may result from exposure to fruit juice. Streaks may indicate that a person brushed their skin against a plant. When the initial symptoms subside, usually after 7-14 days, the skin may show signs of darkening, which is known as hyperpigmentation. This stage of phytophotodermatitis, known as post-inflammatory pigmentation, may last for many weeks or months. Some people who experience only a very mild inflammatory reaction following sun exposure may not even be aware that they have had a reaction. The hyperpigmentation may be the first clue that they have developed phytophotodermatitis. Wet skin, sweat, and heat can exacerbate the initial symptoms, while sun exposure can darken skin pigmentation.
