“…Besides pollen allergens, triggers of florists’ symptoms include sesquiterpene lactones [ 34 ] and parasites of the decorative plants [ 35 ]. Neither skin allergy nor parasites are considered in the current study, which focuses on pollen immunogenicity of the respiratory system [ 16 ]. It is therefore necessary to maintain the position that the portrayal of the decorative flowers as allergens is misleading.…”

“…Plants found on the pictures were identified using botanical and horticultural literature. The identified plant taxa were categorized by their potential allergenicity using the CARE-S index [ 16 ]. In this index, categories are calculated as a function of genetically determined factors of plants: immunogenicity (Im), morphology (Mo) and pollen production (Po).…”

“…The pollen production of cultivars with a high or reduced pollen yield was also considered in the categorization. For a detailed description of the Im, Mo and Po parameters, see [ 16 ]. The combination of these parameters yields the following formula: AC p = Im × Mo × Po where AC p is a raw value of the potential allergenicity which is converted to an index with five categories, referred to as the CARE-S index (CAtegorization System for REgulation of Allergenic Plants by Strong Evidence) ( Table 1 ).…”

“…On the right side, a graph shows the number of cases (occurrence of plant species in allergy-related marketing materials) in allergenicity groups 0–4 plus n.d. (light green–gray graph bands). The potential allergenicity of plants is expressed by the CARE-S index [ 16 ], where 0: non allergenic (light green), 1: low (dark green), 2: medium (yellow), 3: high (orange), 4: very high (red) potential allergenicity, n.d.: no data (gray). The names of individual plant species are not shown (for this, see Table 2 ), but they are grouped according to plant families.…”

Plants are often used to illustrate allergy-related medical products, services, patient information materials and news. The illustration of allergenic plants is an important tool in patient education, contributing to the prevention of pollinosis, as patients can recognize plants and avoid pollen exposure. In this study, it is aimed to evaluate the pictorial content of allergy-related websites depicting plants. A total of 562 different photographs depicting plants were collected using image search, identified and categorized according to their potential allergenicity. Of the total 124 plant taxa, 25% of plants were identified to the genus level and a further 68% were identified to the species level. Plants with low allergenicity were found in 85.4% of the pictures, while plants of high allergenicity were shown in only 4.5% of the pictorial information. Brassica napus was the most frequent species identified (8.9% of the overall identified plants), while blooming Prunoidae, Chrysanthemum spp. and Taraxacum officinale were also common. Considering both allergological and design aspects, some plant species have been proposed for more professional and responsible advertising. The internet has the potential to provide visual support for patient education in allergenic plants, but emphasis must be put on the transmission of the correct visual message.

Allergenic tree pollen in Johannesburg and Cape Town as a public health risk: towards a sustainable implementation framework for South African cities

et al. 2023

South Africa’s urban population is increasing, and in parallel, urban green infrastructure has shown an increase in alien tree species, e.g., mulberry (Morus sp.), oak (Quercus spp.) and plane trees (Platanus spp.) to name a few. This causes ecological problems since alien trees are often more water-demanding and competitive than indigenous trees, but they also increase the abundance of respiratory diseases often triggered by an allergic reaction towards the pollen of those alien taxa. In the current study, utilizing 7-day volumetric spore traps, we illustrate that the most abundant tree pollen in the two largest cities of South Africa, Cape Town and Johannesburg, is produced by alien trees with a high risk of allergenicity. This adds another aspect related to public health when evaluating plant species composition in urban forestry and urban ecology, which underlines the urgency of more intense monitoring. More importantly, this—for South Africa—newly emphasized risk for public health underlines the applicability of current directives [i.e., Spatial Development Frameworks (SDFs), localized Precinct Plans, Land Use Schemes (LUSs)] and implementation options in urban planning. Here, we present ideas that may be implemented in such a framework. From both a public health and an ecological perspective, it is recommended to plant indigenous trees like Combretum erythrophyllum, Vachellia and Senegalia spp. that have fewer ecosystem disservices, like a lower impact on public health due to lower allergenicity/lower pollen occurrence and providing more ecosystem services such as lower water needs.
