Bee pollen can cause a serious allergic reaction in individuals who are allergic to pollen, according to WebMD. Although isolated reports of serious side effects such as kidney and liver damage exist, it is unknown whether bee pollen or some unrelated factor is the true culprit.
Symptoms of an allergic reaction include lightheadedness, shortness of breath, itching, swelling and anaphylaxis, explains WebMD. Pregnant women should not take bee pollen, as some evidence suggests it can stimulate the uterus, threatening the health of the fetus. Women who are breast-feeding should also avoid bee pollen as little is known about its effect on infants. The supplement may cause excessive bleeding in individuals who take blood thinners. Speak with a doctor before taking bee pollen if using over-the-counter, prescription or herbal medications.
Bee pollen supplements are used to treat PMS, hay fever, joint pain, mouth sores, nose bleeds, menstrual problems, prostate conditions, diarrhea, constipation and painful urination, states WebMD. Users also take it as an appetite stimulant, a weight-loss supplement and an anti-aging supplement. Bee pollen is often used in topical skin care products for conditions such as eczema and diaper rash. Contact a doctor before taking bee pollen to determine the appropriate dosage.
