Lipitor is a medication used to lower cholesterol levels in the body. According to the sources provided, there is no evidence to suggest that any herbs can enhance the effectiveness of Lipitor.

Lipitor contains atorvastatin, which works by blocking an enzyme that the liver needs to produce cholesterol. It is a prescription medication and should only be taken under the guidance of a healthcare provider [1].

One of the sources provided, the Mayo Clinic, lists Ginkgo as an herb that may interact with Lipitor. Ginkgo is commonly used to improve memory and cognitive function. However, the Mayo Clinic states that Ginkgo may increase the risk of bleeding when taken with blood-thinning medications, including Lipitor. Therefore, it is important to talk to a healthcare provider before taking Ginkgo or any other herb while on Lipitor [2].

Another source provided, a study published in the National Center for Biotechnology Information, discusses the potential interactions between herbs and statins, a class of medications that includes Lipitor. The study found that some herbs, such as St. John's Wort, may decrease the effectiveness of statins. However, the study did not find any evidence to suggest that any herbs can enhance the effectiveness of statins, including Lipitor [3].

In conclusion, while there are some herbs that may interact with Lipitor, there is no evidence to suggest that any herbs can enhance its effectiveness. It is important to talk to a healthcare provider before taking any herbs or supplements while on Lipitor or any other medication.
