With the change of season we are moving some plants around on Komorebi. We had the chance to harvest some African Wormwood yesterday. I will try to make my very first tincture, the rest will be left to dry. Here is a little more information about this amazing medicinal plant.
🌱Artemisia afra (African Wormwood) is a highly esteemed and widely utilized indigenous medicinal plant across diverse cultures in Africa, especially in South Africa, where it is known by various names such as wilde-als (Afrikaans), umhlonyane (Xhosa/Zulu), and lengana (Sotho). This perennial, aromatic shrub, named after the Greek goddess Artemis, is a prominent member of the Artemisia genus, distinct from other species like Artemisia annua (Sweet Wormwood) in its chemical composition, notably lacking artemisinin.
Botanical Characteristics:
* Artemisia afra typically grows as a soft, bushy shrub, ranging from 0.6 to 2 meters in height, with woody stems at the base and softer branches towards the top.
* Its distinctive silver-grey, finely divided leaves are almost fern-like and emit a strong, sticky-sweet, pungent aroma when bruised. This characteristic scent is a key identifier.
* The plant produces small, inconspicuous, creamy-yellow flower heads in late summer and autumn (March to May in the Southern Hemisphere).
* It is found across a wide geographic area, from South Africa northwards into tropical Africa, often in montane habitats, along forest margins, and by streamsides.
Traditional Medicinal Uses:
Artemisia afra boasts a long and extensive history of traditional use, addressing a vast array of ailments. Its roots, stems, and leaves are prepared in numerous ways, including decoctions, infusions, poultices, body washes, lotions, enemas, or consumed as a tea (often sweetened to counteract its bitter taste). Key traditional applications include:
* Respiratory Ailments: Highly regarded for treating coughs, colds, flu, fever, sore throats, bronchitis, asthma, whooping cough, and croup. Inhaling vapours from infusions or inserting fresh leaves into nostrils to clear blocked passages are common practices.
* Digestive Health: Used to alleviate indigestion, colic, flatulence, stomach pains, and to expel intestinal worms. It also acts as an appetite stimulant.
* Pain and Inflammation: Applied externally as warmed poultices for sprains, arthritic, and rheumatic swellings. Internal use helps with headaches, earaches, and general pain relief.
* Other Uses: Traditionally used for malaria (though scientific efficacy is debated and it lacks artemisinin), diabetes, bladder and kidney disorders, blood purification (for acne and boils), and as a wash for cuts and grazes. It's also used for menstrual issues and post-childbirth recovery.
Other Applications:
Beyond its medicinal value, Artemisia afra is known for its insect-repelling properties. It is used as a natural moth repellent and can be incorporated into homemade insecticide sprays. Dried powdered wormwood is also used to deter ants and fleas.
Cultivation and Sustainability:
Artemisia afra is a hardy and fast-growing plant that thrives in full sun and well-drained soil. It is relatively drought-tolerant once established. Heavy pruning in winter encourages lush new growth. Its widespread use highlights the importance of promoting sustainable harvesting and cultivation practices to ensure its continued availability.
Scientific Research:
While deeply rooted in traditional medicine, scientific research continues to explore the phytochemical composition and pharmacological activities of Artemisia afra. Studies have indicated promising antimicrobial, anti-inflammatory, antioxidant, antidiabetic, and antimycobacterial activities, supporting many of its traditional uses. However, ongoing research is crucial to validate efficacy and safety for specific applications, especially for conditions like malaria, given the lack of artemisinin in this species.
