You’d be hard pressed to find a more nourishing or soothing drink than tea. In fact, this beverage is prescribed for medicinal purposes to patients all over the world. Though you’re bound to feel good after drinking most cups of tea, there are certain varieties that could make you feel even better—and it may just have something to do with your blood type!

I know, I know, it sounds a bit like hocus pocus, but there are some heavy hitters in the medical community that swear by the idea that there are specific diets that align to every blood type.

One well-known doctor has based his successful career off of this type of methodology. Dr. Peter J. D’Adamo is what is called a naturopathic physician—he believes in the power of herbs, exercise, and diet to maintain a healthy lifestyle. He is also the creator of The Blood Type Diet.

Dr. D’Adamo’s studies have shown that a person should have a specialized diet based on their blood type. This diet includes nurturing beverages like tea. Here are some of the doctor’s tea recommendations according to each unique blood type.

Best Teas for Blood Type O

If you have this versatile blood type, then you may suffer from stomach problems. This usually surfaces in diagnoses of acid reflux. To combat this uncomfortable illness, reach for a beverage that is gentle on the stomach, like ginger tea. You will also benefit from sipping a green tea, like Sencha.

Best Teas for Blood Type A

According to Dr. D’Adamo, people with this blood type tend to be overly anxious. If you fall into this category, it is recommended that you drink a Taiwanese tea like jasmine or gunpowder green. You should also consider checking out the fragrant marigold and thyme leaf mixture.

Best Teas for Blood Type B

Folks with type B blood are sometimes described as “slow,” “sluggish,” or “lethargic.” If you identify with any of these symptoms, then consider switching over to green tea. According to Healthy Food House, young green teas are best for these specific ailments. Give red rooibos or organic green a try.

Best Teas for Blood Type AB

Individuals with blood type AB are apparently harder to pin down than their counterparts. The one thing that can be agreed on, though, is that people with this blood type should stay away from drinks that are heavy in caffeine like coffee and black tea. If you have this blood type, focus on drinking young green and herbal teas.

Dr. D’Adamo has built quite an impressive following of devotees. Nonetheless, there have been some questions raised about his rather unusual dietary teachings. In 2014, a Canadian report which spoke out against his diet was released.

Though the idea of the diet may be controversial, many of his cohorts simply swear by it. We say, go ahead and take a gander at your blood type profile. If it rings true for you, then give it a shot! Loading up on healthy tea is definitely a step in a healthy direction!
