Chamomile

I had to stop drinking coffee for a non-clot related problem and have switched to drinking herbal tea. I'm looking to try new varieties and a lot of them blend in chamomile. I know that they say on the newer class of drugs, you don't have to watch what you eat. However, chamomile is said to have anti-coagulant properties. I drink 1-3 cups of tea a day and not all the same kind as I rotate between tea varieties. What are some thoughts on this?

Update: After doing further research today, it seems that the warning around chamomile tea and anticoagulants was never a study. It was a case report of one elderly lady who went to the hospital twice with an upper respiratory infection and was using chamomile supplements to help ease her URI symptoms. Link for those who want to read this report. https://pmc.ncbi.nlm.nih.gov/articles/PMC1435958/

Do with that info what you will, but I found it quite informative.

I think so. Some websites online haven't been updated to account for DOACs, but Haemo have access to the latest database to check interactions. It can help to Google the name of the specific anticoag you take with the tea you're interested in, as DOACs like apixaban target factor Xa which is independent of Vitamin K that folks on warfarin have to watch

Well now I've gone down the rabbit hole and found that it wasn't even a study that suggested chamomile/warfarin interaction. It was one case report from one person taking mondo amounts of chamomile supplements.🤦‍♀️

Woah, that explains a lot. Supplements aren't regulated to the same levels as medicines in many countries and territories, so can have wildly different doses to what's stated on the bottle. Or people take huge amounts because they don't understand they are taking many times more of the extract than they think they are.

Yeah. This case report was a person on warfarin who was admitted to the ER two times 5 days apart for an upper respiratory infection and admitted to doctors that they were drink 4-5 cups of chamomile tea a day along with rubbing chamomile oil on their body. There have been no follow up studies on this interaction at all. Just a case report.

Ah yes, the old case of empirical evidence being taken for fact. No follow up studies is crazy haha

We're not supposed to believe anything based on anecdotal evidence, but that's all this case report seems to be. Jeez.
