r/herbalism on Reddit: Does hibiscus tea thin the blood too much?
January 27, 2023 -
Every time i drink hibiscus tea my veins pop out all over my body. However, my gums swell up and even bleed in some areas, i even cut my finger by accident and blood was coming out like a fountain. I’m not on any medications, i only take few supplements but none of those have blood thinning actions. Please let me know if anyone else experienced that

Additionally, some cultures have used hibiscus tea to reduce the symptoms of hormonal shifts in females, such as PMS and menopause. There is a lack of scientific research on this, though. Hibiscus tea may not be suitable for everyone. It could interact with some medications, and it may cause harm in very high amounts.
