Varför detta händer

Black cohosh and vitamin C are processed by the body through different pathways. Vitamin C is a water-soluble vitamin that does not significantly interfere with the liver enzymes (such as the Cytochrome P450 system) that process black cohosh. Additionally, they do not have overlapping effects that would cause a dangerous build-up or a reduction in effectiveness.

You can continue to take both supplements as directed on the packaging or by your healthcare provider. However, always inform your doctor or pharmacist about all supplements you are taking, especially if you have a history of liver problems, as black cohosh has been rarely linked to liver issues.

Graviditet

Do not use black cohosh during pregnancy. It may stimulate uterine contractions, potentially increasing the risk of miscarriage or premature labour.

Liver disease

Black cohosh has been linked to rare but serious cases of liver failure. You must stop taking it and see a doctor immediately if you develop yellowing of the skin or eyes, dark urine, or severe stomach pain.

Hormone-sensitive conditions (e.g. breast cancer)

Because black cohosh may act like the hormone oestrogen, you should not use it if you have a history of breast cancer, uterine cancer, or endometriosis without specialist medical supervision.

Kidney stones

High doses of vitamin C can increase the amount of oxalate in your urine, significantly raising the risk of developing kidney stones, especially if you have had them before.

Alkohol

Black cohosh has been linked to rare but serious cases of liver damage. Because alcohol also puts strain on the liver, it is advisable to limit or avoid alcohol consumption while taking this supplement to reduce the risk of liver toxicity.
