Buchu Leaves Extract
Also known as: Buchu, Buchu Leaves Extract, Cape Buchu, Agathosma, Buchu Oil, Agathosma betulina
Overview
Buchu is a low shrub native to the Cape region of South Africa, with usage dating back to traditional medicine for various ailments. The dried leaves and essential oil are primarily utilized for managing urinary tract infections, prostate inflammation, and as flavoring agents in food and perfumes. Key active components include volatile oils, ranging from 1.0 to 3.5%, and flavonoids, particularly disophenol, which contribute to its medicinal properties. Although it has been used traditionally for centuries, scientific studies are limited to in vitro and animal research, with a notable absence of human clinical trials, thus making it challenging to fully ascertain its efficacy in human health contexts.
Benefits
Preliminary studies suggest that buchu offers several potential health benefits. It exhibits moderate antimicrobial activity against pathogens like *Bacillus cereus* and *Staphylococcus aureus*, particularly evident in ethanolic leaf extracts. Additionally, it shows anti-inflammatory and anti-diabetic properties that enhance glucose metabolism and help normalize glucose levels in diabetic animal models. Evidence from animal obesity studies indicates that buchu may aid in preventing weight gain and managing hypertension. However, the true effect sizes and clinical relevance in humans remain undefined due to the significant lack of human studies, with the majority of findings stemming from animal research.
How it works
Buchu's antimicrobial activity is primarily attributed to its volatile oils, especially disophenol, which disrupt bacterial cell functions. The compound's anti-inflammatory and anti-diabetic effects are thought to stem from the inhibition of pro-inflammatory cytokines such as IL-6 and TNF-α, along with enhancing cellular glucose uptake. Furthermore, effects related to obesity and hypertension may involve diuretic properties and modulation of adipose tissue, resulting in reduced blood pressure and weight management through various physiological pathways.
Side effects
Buchu is regarded as likely safe when taken in medicinal amounts; however, high dosages and the consumption of essential oils can lead to safety concerns. Common side effects (over 5% incidence) include gastrointestinal irritation, especially when taken on an empty stomach. Less common side effects (1-5% incidence) might involve increased menstrual flow and potential liver damage. Rare occurrences (under 1%) include reports of miscarriages associated with buchu use during pregnancy. Individuals with bleeding disorders, kidney infections, or liver problems should exercise caution, as should those planning for surgery. Pregnant or breastfeeding women are advised to avoid using buchu amounts exceeding typical food consumption levels, and caution is necessary regarding interactions with medications, such as lithium, due to its diuretic effects.
Dosage
Traditional usage recommendations suggest taking 1-2 grams of dried buchu leaves, three times daily, either in capsule form or as tea. Tinctures may also be taken at 2-4 ml, three times daily. However, optimal dosages remain inadequately defined due to the lack of human clinical data. It is advisable to consume buchu extracts with meals to mitigate the risk of gastrointestinal irritation. While higher dosages than those recommended can lead to potential safety issues, the exact toxicity threshold is unclear, underscoring the importance of adhering to specified dosages.
