Red raspberry (Rubus idaeus) is a plant with a history going back thousands of years. According to historians, cave dwellers from the Paleolithic age consumed the fruit for sustenance.1 During the time of Christ, the fruit was gathered in the wild in ancient Troy. As the Medieval Ages came along, red raspberry expanded into the realm of art, where it was used as pigment for paintings and manuscripts.2
The red raspberry that most Americans are familiar with today is believed to be a native North American species, although it also thrives across northern Europe to northwestern Asia.3 George Washington was a notable advocate of this fruit, growing it in his garden.4
You may know red raspberry for its distinctive flavor and color, but that's not all it has to offer. Its leaves are used to make an herbal tea with various potential therapeutic uses. In folk medicine, raspberry leaves were brewed into tea and used to help treat wounds, diarrhea and colic pain.5

The Various Health Benefits of Red Raspberry Leaf Tea
I've written about the benefits of raspberry fruit before, which include the potential to help lower your risk of cancer and a host of inflammatory diseases. However, its leaves possess their own unique traits that make them stand out. Here are some additional benefits you should be aware of when you drink red raspberry leaf tea:
• May boost heart health — Potassium deficiency has been closely associated with high blood pressure and an increased risk of heart disease. In a study published in the journal Hypertension, those who consumed 4,069 milligrams of potassium daily had an impressive 49 percent lower risk of death from ischemic heart disease compared to those who only received around 1,000 milligrams per day.8
• May aid in pregnancy — According to a 1999 study, researchers noted that taking raspberry leaf may help decrease the likelihood of pre- and post-term gestation, as well as reducing the chances of an artificial rupture and the need for a caesarean section.9
However, a 2002 review published in the BJOG journal notes that only a small number of women were involved in the aforementioned study, and it is possible that adverse effects may not have been sufficiently detected. Due to its stimulant effects on the uterus, you should not ingest it during pregnancy without consulting with a physician.10
• Improves digestive function — Red raspberry leaf tea contains various antioxidants that may help manage inflammation throughout your body. In a study published in the Journal of Agricultural and Food Chemistry, researchers noted that red raspberry significantly reduced inflammation in rats affected with antigen-induced arthritis.11
• Helps fight free radicals — Raspberry fruits are known for their antioxidant properties, but did you know that the leaves have these abilities as well? A 2012 study discovered that the leaves exhibit cytotoxic and cytoprotective qualities that may help eliminate free radicals.12
• Lowers risk of blood clots — A study published in Food Chemistry indicates that raspberry leaves contain flavonoids and phenolics that have antithrombotic effects.13
Red Raspberry Leaf Tea Nutrition Facts
Red raspberry leaf tea is a caffeine-free beverage.14 It's also low in calories, which may help support healthy weight management. However, it is somewhat lacking in other nutrients. With that in mind, red raspberry leaf tea is best used as a tool to help augment your antioxidant profile while you obtain essential nutrients from other foods.
How to Grow and Store Red Raspberry Leaf Tea
Growing raspberry plants in your own home will be advantageous because you not only will have a clean source of tea leaves, but you can also enjoy the berries in their freshest state. To start cultivating the plants, make sure that your garden has rich, organic soil with a pH level of 5.8 to 6.5. In addition, the area must get six to eight hours of sunlight per day.15
Plant seeds in the early spring, and water the soil regularly to help prevent weeds from overpowering the raspberries once they mature. Lastly, make sure that they're not planted near other plants such as tomatoes and potatoes because they're prone to the same fungus that raspberries are susceptible to.16
Harvest the leaves during the spring before flowers emerge, choosing only those that are young, bright and green. Make sure to get a little more than what you need because the drying process shrinks them. To prepare for storage, dry the leaves by placing them in your oven on a cookie sheet. Use the lowest heat setting, checking regularly every 15 to 20 minutes until the leaves become crispy. Afterward, allow the batch to cool.17
To properly store your dried leaves, you need to grind them first. The easiest way to do this is putting them in your food processor, but you can also use a mortar and pestle. Place the leaves in an airtight container to maintain freshness.18
