2023年2月28日，据欧盟食品安全局（EFSA）消息，应欧盟委员会要求，欧盟动物饲料添加剂和产品（FEEDAP）研究小组就刺五加根酊剂（a tincture derived from the roots of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim.）作为狗、猫和马饲料添加剂的安全性和有效性发表科学意见。
经过评估，专家小组得出结论，在建议的使用条件下该添加剂对目标物种和消费者是安全的。由于刺五加的根具有调味特性，其在饲料中的功能与在食品中的功能基本相同，因此认为没有必要进一步证明其功效。部分原文报道如下：
Following a request from the European Commission, EFSA was asked to deliver a scientific opinion on the safety and efficacy of a tincture from the roots of Eleutherococcus senticosus (Rupr. & Maxim.) Maxim. (taiga root tincture) when used as a sensory additive in feed for dogs, cats and horses. The Panel on Additives and Products or Substances used in Animal Feed (FEEDAP) concluded that the additive is safe for dogs, cats and horses at the maximum proposed use level of 460.7, 489.5 and 140.7 mg/kg complete feed, respectively. The additive was considered safe for consumers when used at the proposed conditions of use in horses for meat production. The additive under assessment should be considered as irritant to skin and eyes, and as a skin and respiratory sensitiser. The use of the taiga root tincture as a flavour in feed for horses was not expected to pose a risk for the environment. Since the root of E. senticosus has flavouring properties and its function in feed would be essentially the same as that in food, no further demonstration of efficacy is considered necessary for the tincture under assessment.
