Consumers and health professionals are advised that, following a safety review of Andrographis paniculata (A.paniculata), the TGA has found a potential risk of allergic reactions, including severe allergic reactions such as anaphylaxis, associated with the use of products containing this herbal ingredient.
A.paniculata is a herbal ingredient used in some complementary medicines. It belongs to the Acanthaceae family and is indigenous to India, Ceylon, and Java. A.paniculata is also known as kalmegh and green chiretta in Ayurvedic medicine, and chuanxinlian in traditional Chinese medicine.
A.paniculata has been used traditionally to:
- relieve fever
- relieve the symptoms of colds
- alleviate sore throats
- alleviate gastro-intestinal upsets and acute diarrhoea
- aid recovery from mild respiratory tract infections.
Products that include A.paniculata are listed on the Australian Register of Therapeutic Goods (ARTG) with a wide range of indications.
There are currently no restrictions or label warnings required for the use of A.paniculata in medicines in Australia.
Between December 2002 and April 2014, the TGA received 43 reports of anaphylaxis and 78 reports of other allergic-type reactions associated with products that contain A.paniculata.
The TGA safety review, which included analysis of the above reports, indicated that A.paniculata might cause or play a contributing role in these adverse reactions, including when used in multi-ingredient formulations.
This issue was also referred to the Advisory Committee on the Safety of Medicines, (ACSOM) which considered the information and provided advice regarding potential actions to reduce the risk. Details of this advice are available in the ACSOM Meeting 23 meeting statement on the TGA website.
The TGA is now considering whether any further action is required, and in the meantime will continue to monitor products containing A.paniculata.
