From .oncology: Fennel (Foeniculum vulgare) is a plant from the carrot family that you are likely familiar with if you have any significant history of cooking experience, as it is known for its strong flavor. In herbal medicine, fennel has a long history of use for digestive issues such as heartburn, gas and bloating, and loss of appetite. In 2015, a group of Chinese researchers decided to investigate this common digestive aid and whether it could potentially help patients with gynecological cancers recover from major surgery.
The study included 159 women, who were randomized to a tea group or a control group. The tea group drank two cups of fennel tea per day, beginning the day after surgery and continuing until the first flatus (i.e. passing gas). What the researchers found was that the addition of fennel tea in the post-surgical setting significantly improved multiple post-surgical outcomes. In addition, the control group was significantly more likely to have symptoms of ileus, a term referring to the lack of movement in the intestines, which can lead to intestinal obstruction. In summary, a cup of tea allowed women to leave the hospital and return home a full day earlier and significantly reduced their risk of complications. A cup of tea!
Fennel is generally considered a safe herb to take, but there are some notable cautions. First, due to estrogenic activity found in some of its components, a patient with a hormone receptor-positive cancer would be advised against taking fennel in large doses or over an extended period of time. Second, animal research suggests fennel in high doses may have some blood-thinning properties, so it would be best to avoid in the pre-surgical setting and in patients with bleeding disorders. Lastly, a patient who is allergic to celery, carrot, or mugwort should not take fennel. Despite these cautions, fennel tea appears to be an ideal post-surgical recommendation for patients undergoing surgery for gynecological cancers considering its simplicity, safety, affordability, and efficacy!
