Kombucha tea, especially batches made at home where it's hard to maintain a germ-free environment, can become contaminated with fungus (Aspergillus) and bacteria (including anthrax). In Iran, 20 people got anthrax infections from taking kombucha tea. This tea is LIKELY UNSAFE in people with weakened immune systems, such as people with HIV/AIDS, who are more likely to get infections, as well as when it is prepared in a lead-glazed ceramic pot. Lead poisoning has been reported following ingestion of kombucha tea.
Special Precautions & Warnings:Pregnancy and breast-feeding: Kombucha tea is POSSIBLY UNSAFE during pregnancy and breast-feeding. Stay on the safe side and avoid use.
Alcoholism: Kombucha tea contains alcohol. Avoid it if you have a drinking problem.
Diabetes: Kombucha tea might affect blood sugar levels in people with diabetes. Watch for signs of low blood sugar (hypoglycemia) and monitor your blood sugar carefully if you have diabetes and use kombucha tea.
Diarrhea: Kombucha tea contains caffeine. The caffeine in kombucha tea, especially when taken in large amounts, can worsen diarrhea.
Irritable bowel syndrome (IBS): Kombucha tea contains caffeine. The caffeine in kombucha tea, especially when taken in large amounts, can worsen diarrhea and might worsen symptoms of IBS.
Surgery: Since kombucha tea seems to affect blood glucose levels, there is a concern that it might interfere with blood glucose control during and after surgery. Stop using kombucha tea at least 2 weeks before a scheduled surgery.
Weak immune system: Don't use kombucha tea if you have a weakened immune system due to HIV/AIDS or other causes. Kombucha tea can support the growth of bacteria and fungus that can cause serious infections.
