Smodingium argutum is the plant most commonly responsible for causing acute allergic contact dermatitis in South Africa. When an outbreak of Smodingium dermatitis occurred in a local school the allergenic principle present in this plant was chemically isolated and identified, and its allergenic property proved in the clinic by patch testing. The value of using an extract of fresh Smodingium leaves in lieu of fresh leaves themselves was confirmed, but freeze-dried material was found to be unsuitable for patch-test purposes.
刺苞蓟是南非最常导致急性过敏性接触性皮炎的植物。当当地一所学校爆发刺苞蓟皮炎时，从这种植物中化学分离并鉴定出了致敏成分，并通过斑贴试验在临床上证实了其致敏特性。使用新鲜刺苞蓟叶提取物代替新鲜叶子本身的价值得到了证实，但发现冻干材料不适用于斑贴试验。
