2019年12月6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）研究小组就一种从毛蕊花（Verbascum thapsus L.）中提取的酊剂作为所有动物物种的感官饲料添加剂的安全性和有效性发表科学意见。

 

　　据了解，该产品为水/乙醇溶液，干物质含量约为2.8%。由于一些数据的缺乏，专家小组无法确定该添加剂的安全性。而该种添加剂的主要成分能够在食品中作为风味物质，其在饲料中的作用基本相同，因此没有必要证明其功效。部分原文报道如下：

 

　　Following a request from the European Commission, the EFSA Panel on Additives and Products or Substances used in Animal Feed （FEEDAP） was asked to deliver a scientific opinion on the safety and efficacy of a tincture from Verbascum thapsus L. （great mullein tincture） when used as a sensory feed additive for all animal species. The product is a water/ethanol （■■■■■） solution, with a dry matter content of approximately 2.8%. The product contains on average 0.216% polyphenols and 0.093% flavonoids. Since 82% of the dry matter fraction of the additive remains uncharacterised, the FEEDAP Panel cannot identify a safe level for the use of the additive for all animal species. Considering the uncertainty in the composition of the additive, and in the absence of information on the toxicological properties of the tincture, the FEEDAP Panel is unable to conclude on the safety for the consumers following the use of the tincture as flavouring in animal feed. No specific data were provided by the applicant regarding the safety of the additive for users. In the absence of data, no conclusions can be drawn on the additive's potential to be a dermal/eye irritant or a skin sensitiser. V. thapsus L. is native to Europe. Consequently, the use of a tincture derived from the plant at the maximum proposed dose is not considered to be a risk for the environment. Since the major components of the additive are recognised to provide flavour in food and its function in feed would be essentially the same, no demonstration of efficacy is considered necessary.
