Can Eating Too Much Fennel Seed Be Harmful?

Serious fennel seeds side effects aren’t common.
As with any herbs or seeds that you use in large quantities, it’s important to use a trusted supplier and to pay attention to any recalls. In 2019, the Food and Drug Administration put out a warning that an online supplier of herbs was recalling recent fennel seed purchases. A large lot of seeds may have been infected with salmonella, the supplier found.
Tip
Serious fennel seeds side effects aren’t common. But some people may experience allergies or other side effects.
Understanding Fennel Seeds’ Side Effects
As with other ingredients, especially those that have both medicinal and culinary uses, research has been done on both fennel seeds’ benefits and many of fennel seeds’ disadvantages. In terms of potential fennel seeds’ side effects, they include:
- Carcinogen concern: A November 2018 review of research published in the Annals of Complementary and Alternative Medicine (ACAM) examined a compound found in fennel seeds, known as estragole, as a possible carcinogen. The European Medicine Agency has guidelines on safe amounts of estragole in fennel seeds, given that the natural compound can fluctuate within the fennel plant and its seeds. Most people do not exceed the safe amount of estragole through fennel consumption, according to ACAM. In addition, studies on mice in which liver tumors were caused by pure estragole may not be relevant, because humans appear to metabolize the compound more rapidly. If you use fennel seeds in abundance, asking your doctor about the issue may be relevant, depending on your medical history.
- Nipple discharge: Women, men and even children can get a condition known as galactorrhea, which causes a milky substance to leak from their nipples. Stimulating milk production is seen as one of many fennel benefits for nursing mothers, which is why it’s included in some lactation tea blends. But a similar hormonal reaction from ingesting large amounts of the seeds can potentially become an unwelcome fennel seed disadvantage.
- Sun sensitivity: If you take fennel seed regularly, you may be more prone to burning if you don’t wear sunscreen in bright conditions, or if you visit a tanning bed.
- Drug interactions: Because herbs and spices aren’t regulated by the Food and Drug Administration, there aren’t many official government agency warnings about drug interactions with fennel seeds. The pharmaceutical database Drugs.com suggests that women taking birth control pills use caution, because the seeds may make the pills less effective. Other potential drug interactions include Tamoxifen, a breast cancer treatment drug, and Ciprofloxacin, an antibiotic.
Warning
It’s crucial to pick a reputable provider and to be aware of any recalls when using big quantities of any herbs or seeds. The Food and Drug Administration issued a warning in 2019 informing consumers that a retailer of herbs online was recalling recently bought fennel seed. The supplier discovered that there may have been a huge batch of salmonella-contaminated seeds.
Are You Feeling Tingly?
Unaware that their symptoms are allergic ones or that fennel seed may be the cause, some persons suffer allergies to the fennel seed. The mouth and nose are where allergies to herbs and spices usually manifest themselves. Keep a food journal to check if fennel seeds or other substances you commonly consume may be to blame if your nose or sinus canals frequently feel itchy. The same safety measures apply if your lips enlarge, your tongue feels tingly or numb, or you experience any of these symptoms.
Fennel is listed in two categories of allergies by the Mayo Clinic, both of which are connected to pollen. The first is the birch family, which also contains various fruits, nuts, and root vegetables as well as the other herbs and spices often associated with fennel, such as anise, parsley, coriander, and caraway. The second category is the mugwort family, which also includes cruciferous vegetables, garlic, onions, certain fruits, fennel, and similar herbs and spices.
Additional food allergy symptoms can include hives on other parts of your body, an upset stomach, and wheezing in addition to swelling and tingling in your mouth and face. You can also develop increased sensitivity to sunlight. Extreme signs can include fainting or a sharp drop in blood pressure. It’s crucial to seek prompt medical attention for serious reactions.
