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 have been taking 40 mg of black cohosh for two months. It has worked very well for night sweats and slight moodiness. The only side effect could be weight gain. I am up a couple of pounds with no changes other than taking black cohosh. However, the weight gain could just be menopause. I did try a stronger dose at first, 940 mg, because that is all I could find. Within a month, I had severe dizziness, so I went down to my current dosage. Seems to be working just fine. To me, this is a lifesaver."

For Postmenopausal Symptoms "I started taking black cohosh to help ease hot flashes. I'm almost a week in, and although the hot flashes eased off a tiny bit, the side effects are horrendous. I've been waking up with excruciating headaches that taper off really slowly throughout the day. I'm constantly rushing to the bathroom due to diarrhea. Stomach is crampy and gassy, and experiencing bouts of dizziness. I tossed them in the trash this morning. I'll take the hot flashes over the debilitating side effects any day."

For Postmenopausal Symptoms "I started taking black cohosh for hot flashes and night sweats as recommended by my doctor. I’m about 1 month in, and the side effects are headaches, cramps, palpitations, increased blood pressure, and dizziness. I have stopped taking it and will suffer with the hot flashes... I do not recommend it at all."

For Herbal Supplementation "Started taking 7 days ago, and yes, the hot flushes have eased. I feel quite ill, to be honest-severe dizziness, diarrhea, heart palpitations, and chest pains. Didn't think it was the black cohosh until I read other reviews. Stopping taking these. Would rather put up with the hot flushes."

For Postmenopausal Symptoms "Took one pill for the first time to treat hot flashes and night sweats. While I haven't had any hot flashes today, I have had a headache all day and one bout of dizziness. I overall feel tired and like I have lead in my shoes. I don't think it's worth the trade-off."

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."
