經過評估，專家小組認為在建議的使用條件下該添加劑對目標物種和環境是安全的。由於其在飼料中的功能與在食品中的功能基本相同，因此認為沒有必要進一步證明其功效。部分原文報道如下：

 

　　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 an essential oil from the leaves of Agathosma betulina (P.J. Bergius) Pillans (buchu leaf oil), when used as a sensory additive (flavouring) in feed and water for drinking for all animal species. The FEEDAP Panel co ncluded that the essential oil under assessment is safe up to the maximum proposed use levels in complete feed of 0.1 mg/kg for chickens for fattening, 0.15 mg/kg for laying hens, turkeys for fattening and rabbits, 0.20 mg/kg for piglets, 0.25 mg/kg for pigs for fattening, 0.30 mg/kg for sows and dairy cows, 0.45 mg/kg for cattle for fattening, sheep, goats and horses, 0.5 for veal calves (milk replacer), fish, ornamental fish and dogs. For cats, the calculated maximum safe level in feed is 0.2 mg/kg complete feed. The FEEDAP Panel co nsidered that the use in water for drinking is safe provided that the total daily intake of the additive does not exceed the daily amount that is co nsidered safe when co nsumed via feed. No co ncerns for co nsumer safety were identified following the use of the additive up to the highest safe levels in feed. The essential oil under assessment should be co nsidered as irritant to skin and eyes, and as a skin and respiratory sensitiser. The use of the additive in animal feed under the proposed co nditions was not expected to pose a risk for the environment. Buchu leaf oil was recognised to flavour food. Since its function in feed would be essentially the same as that in food, no further demo nstration of efficacy was co nsidered necessary.
