The weeping fig, Ficus benjamina (Fb), is a relatively common indoor allergen. Many cases of perennial allergic rhinoconjunctivitis and allergic asthma caused by Fb hypersensitivity are not detected. These patients typically have proven sensitization to housedust mites and do not improve after avoidance of exposure (encasing) and specific immunotherapy. The number of Fb sensitizations is increasing in Germany, which can partly be explained by the cross-reactivity between Hevea brasiliensis (Hb) latex and Fb and the rapidly increasing number of mostly occupational latex allergies. But Fb itself is a potential sensitizer which is widely spread as ornamental plant in homes and offices. As relevant indoor allergen Fb ranks third after housedust mites and pets but before molds among our allergy patients. For diagnosis, prick-tests with Fb-latex seem to be more sensitive than in vitro-methods (RAST, CAPRAST). Fb plants should not be kept in the homes of atopic individuals or persons with latex (Hb) allergy.
垂叶榕，即小叶榕（Fb），是一种相对常见的室内过敏原。许多由Fb过敏引起的常年性变应性鼻结膜炎和过敏性哮喘病例未被检测出来。这些患者通常已被证实对屋尘螨过敏，在避免接触（封装）和特异性免疫治疗后病情并未改善。在德国，对Fb过敏的人数正在增加，部分原因可解释为巴西橡胶树（Hb）乳胶与Fb之间的交叉反应，以及主要是职业性乳胶过敏的人数迅速增加。但Fb本身就是一种潜在的致敏原，作为观赏植物在家庭和办公室中广泛分布。在我们的过敏患者中，作为相关的室内过敏原，Fb在屋尘螨和宠物之后排名第三，但在霉菌之前。对于诊断，用Fb乳胶进行点刺试验似乎比体外方法（放射变应原吸附试验、CAP变应原吸附试验）更敏感。Fb植物不应放置在特应性个体或对乳胶（Hb）过敏者的家中。
