Sixteen patients with verified light sensitivity to both UVB and UVA wavebands showed allergic reactions to various lichen plants (Parmelia spp., Hypogymnia spp., Pseudovernia spp., Cladonia spp., Platismatia spp., Physcia spp., Umbilicaria spp. and Cetraria spp.). Among the aromatic lichen compounds, atranorin was observed to be the most frequently involved allergen, but also several other isolated lichen acids were immunologically active: d-usnic, evernic, stictic, fumarprotocetraric, lobaric, salazinic, diffractaic and physodic/physodalic acid. Several patients showed allergy to other plant substances from other sources such as seven different species from the Compositae family, alantolactone, balsam of Peru, colophony and wood tars. Sensitivity to known photosensitizers was observed in four patients. Aromatic lichen acids are UV-absorbing substances and several are evidently able to photosensitize human skin.
16名经证实对UVB和UVA波段均有光敏感的患者对多种地衣植物（梅衣属、裸果衣属、假花松萝属、石蕊属、扁枝衣属、绵腹衣属、脐衣属和冰岛衣属）出现过敏反应。在地衣芳香化合物中，松萝酸被观察到是最常涉及的过敏原，但其他几种分离出的地衣酸也具有免疫活性：右旋松萝酸、扁枝衣酸、地衣硬酸、富马原岛衣酸、大叶地衣酸、柳珊瑚酸、柔扁枝衣酸和绵腹衣酸/石面酸。有几名患者对其他来源的其他植物物质过敏，例如菊科的7个不同物种、阿兰内酯、秘鲁香脂、松香和木焦油。在4名患者中观察到对已知光敏剂的敏感性。地衣芳香酸是紫外线吸收物质，其中几种显然能够使人类皮肤产生光过敏反应。
