Organic Vervain Aerial Parts Extract
Also known as: Vervain, Common Vervain, *Verbena officinalis*
Overview
Verbena officinalis, commonly known as vervain, is a medicinal herb widely distributed around the globe. This plant is traditionally utilized in folk medicine for its numerous therapeutic effects. Its aerial parts are rich in bioactive compounds such as iridoids, phenylpropanoid glycosides, phenolic acids, flavonoids, terpenoids, and essential oils, which contribute to its antioxidant, antimicrobial, anti-inflammatory, and potential anticancer properties. Although it has applications in food and cosmetics, its use in herbal medicine has been documented for centuries. The current research on vervain is moderate, heavily leaning towards in vitro and animal studies with limited human trials, indicating a need for further investigation to fully understand its potential therapeutic benefits.
Benefits
The primary benefits of vervain include its potential antitumor effects, which have been indicated in animal studies where high doses of the extract inhibited tumor growth by over 30%. Additionally, vervain shows promising neuroprotective effects, thereby assisting in recovery after strokes through new blood vessel development. Secondary benefits noted in animal studies include anxiety reduction comparable to diazepam and significant antimicrobial activity against a broad spectrum of bacteria and fungi. Despite the encouraging results, human studies remain scarce, necessitating further research to confirm these effects in populations with specific health conditions.
How it works
Vervain is believed to exert its effects via several biological pathways, including antioxidant, anti-inflammatory, and antimicrobial mechanisms. The bioactive compounds, such as verbenosides and triterpenoids, may interact with various biological systems, including the nervous, immune, and cardiovascular systems, targeting cancer cells and inflammatory responses. However, specific molecular targets and the bioavailability of these compounds in humans require more thorough investigation.
Side effects
The safety profile of vervain is generally regarded as favorable, though human data is limited. Common side effects are not well-documented, but gastrointestinal upset is a potential concern in about 1-5% of users. Rare side effects are also not well-documented. There are concerns regarding possible interactions with blood thinners and diabetes medications due to its antioxidant properties. Moreover, contraindications exist for pregnant and breastfeeding individuals due to inadequate safety data. Individuals with allergies to plants from the Verbenaceae family should use caution.
Dosage
Current literature does not establish a minimum effective dose of vervain in humans, and the optimal dosage ranges vary significantly based on preparation methods, whether it be in teas, extracts, or capsules. Maximum safe dosages remain undefined, due to limited research. Furthermore, there are no specific timing recommendations for consumption, but bioavailability may be influenced by the method of preparation. Users are encouraged to follow guidelines provided by healthcare professionals regarding dosages and methods of administration.
