Lipitor, also known as atorvastatin, can have interactions with certain herbs. These interactions can impact the effectiveness of Lipitor or increase the risk of side effects. It is crucial to consult with a healthcare provider before combining Lipitor with any herbal supplements.

According to the National Health Service (NHS) and Medical News Today, some herbs can interact with Lipitor. These herbs include:

1. St. John's Wort [1][2]: This herb can reduce the effectiveness of Lipitor by speeding up the breakdown of the medication in the body. As a result, the cholesterol-lowering effects of Lipitor may be reduced.

2. Red Yeast Rice [1][2]: This herbal supplement contains a natural form of statin, which can increase the risk of side effects such as muscle pain and liver damage when taken with Lipitor.

3. Garlic [1][2]: Garlic may also increase the risk of side effects when taken with Lipitor, as it can lower cholesterol levels and potentially interact with the medication.

4. Ginkgo Biloba [1]: Ginkgo Biloba might increase the risk of bleeding when taken with Lipitor, as both substances can affect blood clotting.

5. Saw Palmetto [1]: Saw Palmetto may interact with Lipitor and increase the risk of side effects, particularly when used for an extended period.

It is essential to consult a healthcare provider before combining Lipitor with any herbal supplements, as interactions can occur even with herbs not listed here. Always provide a complete list of medications and supplements to a healthcare provider to ensure safe and effective treatment [1][2][3].
