A Chinese translation 中文翻译 of this information is available below.
The Therapeutic Goods Administration (TGA) is warning consumers and health professionals that listed medicines containing the herbal ingredient Eucommia ulmoides may pose a risk for individuals with a latex allergy or sensitivity.
Eucommia ulmoides (also known as Du-Zhong or Tu-chung) is permitted for use in listed medicines in Australia. The TGA has recently become aware that the Eucommia ulmoides plant which makes up the herbal ingredient contains naturally occurring latex. It is not currently required that the presence of latex be declared on medicine labels. Exposure to latex can cause severe and sometimes life-threatening reactions in individuals with a latex allergy and should be avoided, particularly exposure to the mouth. Allergic reactions to latex can vary and include immediate reactions, including anaphylaxis when severe, as well as irritant dermatitis and allergic contact dermatitis. All types require avoidance of contact with latex to prevent an allergic reaction.
Listed medicines that contain Eucommia ulmoides are available from a range of suppliers, including through health food stores and Traditional Chinese Medicine (TCM) practitioners. Eucommia ulmoides has been traditionally used for a variety of conditions, including for purported anti-inflammatory effects and relief of minor arthritic conditions.
The latex that is commonly used in commercial rubber products is obtained from a different plant, and the extent to which people with a latex allergy will react to latex in Eucommia ulmoides is still under investigation. As part of this investigation, the TGA is considering whether a label statement is needed to declare the presence of latex in listed medicines that contain Eucommia ulmoides. In the meantime, the TGA considers it prudent for individuals with a latex allergy to avoid Eucommia ulmoides given the potential for an allergic reaction. To date the TGA has received one report of an allergic reaction associated with a listed medicine that contained Eucommia ulmoides along with several other ingredients.
