Lipitor is a commonly prescribed medication for high cholesterol, and it is important to know which herbs can interact with it. According to the sources provided, there are several herbs that may interact with Lipitor.

The first source [1] provides a list of drug interactions with Lipitor, but it does not mention any herbs. However, the second source [2] discusses the potential interactions between atorvastatin (the active ingredient in Lipitor) and several herbs. The article states that St. John's Wort, garlic, and guggul may reduce the effectiveness of atorvastatin. St. John's Wort and garlic are commonly used as natural remedies for various health conditions, while guggul is used in traditional Indian medicine. However, these herbs should be avoided or used with caution if taking Lipitor.

The third source [3] also mentions the potential interaction between Lipitor and St. John's Wort. It states that St. John's Wort may decrease the effectiveness of Lipitor, and it is recommended to avoid taking them together. The article also mentions that other herbs, such as echinacea and ginkgo biloba, may interact with Lipitor, but the evidence is not clear.

In conclusion, it is important to be cautious when taking Lipitor with herbs. St. John's Wort, garlic, and guggul may reduce the effectiveness of Lipitor, and should be avoided or used with caution. Other herbs, such as echinacea and ginkgo biloba, may also interact with Lipitor, but more research is needed to determine the extent of the interaction. If you are taking Lipitor and considering using herbal supplements, it is recommended to consult with your healthcare provider first.
