Originally isolated from the Pacific yew tree, paclitaxel (marketed as Taxol®) was initially established as a cytotoxic chemotherapy drug that disrupts cell division. However, modern research reveals a more complex picture, raising the question: **Is paclitaxel a chemotherapy or immunotherapy?** The answer is nuanced, as evidence shows it functions as chemotherapy but also possesses immunomodulatory properties that can be exploited in combination with other therapies.

In vitro studies show that docetaxel can be more potent than paclitaxel in promoting microtubule assembly, a key mechanism for fighting cancer cells [1.6.1, 1.2.4]. The question of if docetaxel is stronger than Taxol (paclitaxel) is complex, with the answer depending on the cancer type, clinical setting, and patient-specific factors.

In December 1992, the U.S. Food and Drug Administration (FDA) first granted approval for the brand-name drug Taxol (paclitaxel) for the treatment of refractory ovarian cancer. The medication's journey from a rare tree bark to a life-saving chemotherapy, however, began decades earlier, marked by scientific breakthroughs, supply challenges, and significant milestones.

In the 1960s, a joint program between the National Cancer Institute (NCI) and the U.S. Department of Agriculture (USDA) began screening thousands of plant extracts for anti-cancer properties. One sample, from the slow-growing Pacific yew, was found to be active, sparking the incredible history behind the question: what tree does Taxol come from?.

First isolated from the bark of the Pacific yew tree in the 1960s, the journey to answer 'How long has Taxol been around?' reveals a multi-decade saga of scientific discovery and development that transformed cancer treatment [1.2.1, 1.10.2].
