In the Middle Ages, it was commonly used to expel intestinal worms, hence the name ‘Wormwood’. Additionally, its antibacterial and antifungal qualities made it a popular choice for preventing infections.
Historically, Wormwood also played a pivotal role in the creation of absinthe, a potent alcoholic beverage famously associated with artists and writers in the 19th and early 20th centuries. Its use in absinthe provided not only flavor but was also thought to stimulate creativity, although it later became controversial due to health concerns linked to its psychoactive effects.
Sweet Wormwood in history
Sweet Wormwood, or Artemisia annua, has a distinctly different history, most notably in Chinese medicine where it’s known as Qing Hao. It has been used since ancient times, primarily for treating fevers. The earliest record in the “Handbook of Prescriptions for Emergency Treatments” written in 340 AD by Ge Hong, details its use in a simple tea to alleviate fever symptoms.
In recent history, Sweet Wormwood gained international attention when its extract, artemisinin, was found to be remarkably effective against malaria. This discovery was pivotal in modern medicine and earned the 2015 Nobel Prize in Physiology or Medicine for the scientist who rediscovered its uses, Dr. Tu Youyou.
Botanical Differences
Physical characteristics
Wormwood and Sweet Wormwood, while related, display notable differences in their physical makeup. Artemisia absinthium is characterized by its silvery-green leaves with fine silky hairs and yellow-green flowers. It typically grows as a bushy plant with a robust, woody base. The plant exudes a strong aromatic scent that is somewhat bitter.
In contrast, Sweet Wormwood, Artemisia annua, is taller and less bushy, with a more annual growth habit. Its leaves are more finely divided and it has a sweeter scent, lacking the intense bitterness of its cousin. The flowers are small and pale, making it less visually striking than traditional Wormwood.
Geographic distribution
Geographically, Wormwood is native to Eurasia and North Africa, thriving in arid conditions typical of a steppe-like environment. It is robust and can survive in poor soils, which has allowed it to spread widely across continents.
Sweet Wormwood, on the other hand, is more prevalent in Asia, particularly in China, Vietnam, and parts of India. It prefers a temperate climate and has been cultivated extensively in these regions for its medicinal properties.
Chemical Components
Key compounds in Wormwood
The primary bioactive compounds in Wormwood include thujone, sabinene, and sesquiterpene lactones, which contribute to its medicinal and toxicological properties.
