For Postmenopausal Symptoms "I began taking black cohosh about 2 months ago for hot flashes. I just stopped taking it today. I have figured out that it must be the black cohosh making me sick. At one point, I thought I had COVID-19! I was tested and was negative. I have been suffering from cramps, diarrhea, headache, constipation, rash, nausea, extreme feeling of heaviness, dizziness, and weight gain! I had no idea black cohosh had horrible side effects for many. I’ll take the hot flashes any day over these side effects. I am probably going to go back on an estrogen patch or cream. I came off of the patch about 4 years ago for safety and health reasons."

For Postmenopausal Symptoms "I started taking Black Cohosh to relieve hot flashes and night sweats. Within about 12 hours after taking my first dose, I felt dizzy and nauseous. It has taken me about 5 days to link it to Black Cohosh."

For Herbal Supplementation "I started black cohosh 1 week ago for perimenopause and just realized, after thinking I was experiencing a kidney infection or maybe even about to pass a stone, that it is from this supplement! I've never had any issues with either my entire life, but something has been very wrong. Very nauseous, daily throbbing headaches, and extremely bloated! I am so thankful something told me to look this up! In the trash they shall go!!!!"

For Postmenopausal Symptoms "I took 150 mg a day for about a week when I woke up one morning with debilitating dizziness. I could barely move all day. The next day was a tiny bit better, but this continued for several days. I thought I had vertigo! I was a little nauseous, so dizzy, headaches, felt heavy, was retaining water, my stomach was bad, and I was so bloated (the way I used to feel before my period). I finally realized that it must be the black cohosh, and sure enough, read about all the possible side effects that I didn’t know about. I stopped taking it about 5 days ago, and I’m very slowly starting to feel better. If you are someone who is sensitive to medication, DO NOT TAKE THIS!! It literally made me sick."

For Herbal Supplementation "I started taking this in hopes that it would help my horrible PMS. It didn’t, but it did get me pregnant! I had tried everything else and gave up on that dream, but still wanted to sort out my hormones. It did make me nauseous, and my reflexologist could feel a change in my liver after it, but the end result was worth it. Everyone’s chemistry is different, so you have to be a scientist and experiment."

"Within 24 hours, started heavily spotting, within 48 hours, still spotting heavily (as much as a heavy menstrual cycle) with migraine and nausea. Within 4 days, rash across my face and neck, and still spotting, so I stopped taking it. Headaches/migraines/nausea stopped, so did spotting, and I felt enormously improved. I did experience slightly elevated mood while taking it, but the side effects were too extreme. I’ve not spotted mid-cycle before, so I’m confident in the causation. I am not menopausal but show some pre-/peri-menopause symptoms (irregularity is not one of them), such as lower estrogen."

For Postmenopausal Symptoms "Black cohosh did not work. I took one pill for four nights. My belly swelled bigger every day. I was violently ill. Vomiting, headache 1,000 times worse than a migraine for 10 hours, and diarrhea. It's been four days, and I am still nauseous. Antacids, dry toast, and chicken soup are all I can stomach. I cannot wait for it to wear off. Never again will I try voodoo witch doctor remedies."
