Buttercup is a plant. People dry the parts that grow above the ground and use them for medicine. Fresh preparations are very irritating and should not be used.
How does it work?
Buttercup contains toxins that are very irritating to the skin and the lining of the mouth, stomach, and intestines. There is not enough information to know how buttercup might work for medicinal uses.
Insufficient Evidence to Rate Effectiveness for...
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Fresh buttercup is UNSAFE. It may cause severe irritation of the digestive tract, with colic and diarrhea. Irritation of the bladder and urinary tract can also occur. Skin contact may cause blisters and burns that are difficult to heal. It can also increase the risk of sunburn.
Some of the toxins in fresh buttercup might be destroyed in the drying process, but there isn't enough information to know if dried buttercup might be safe.
The appropriate dose of buttercup depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for buttercup. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
