Coffee. Coffee used to be maligned because of its caffeine content, but more recent evidence suggests it protects against liver disease and has positive effects on cardiovascular disease and even mortality. (See Dr. Malone’s article for references.) There are no randomized trials, however, so we can’t be entirely sure if these associations are causal, but at least I can feel better about the 4 cups of coffee I drink every day!
Tea, especially green tea, appears to have many positive effects on health, including potential roles in reducing the risk of cancer, cardiovascular disease, type 2 diabetes, and even dementia. As with coffee, these associations are based on large observational studies and not randomized trials.
Chamomile. If your coffee gives you too much of a buzz and causes you to feel anxious, calm down with chamomile tea or oil. Evidence from randomized trials indicates it has positive effects on insomnia and anxiety.
Peppermint oil. The data for calming irritable bowel syndrome is fairly strong, and it may be effective in aborting migraines when applied to the forehead. It’s certainly worth a try for these difficult-to-treat conditions.
When patients ask you about botanicals and herbals, a great resource is the Natural Medicine Database (https://naturalmedicines.therapeuticresearch.com).
Now I will finish my fourth cup of coffee . . .
