Anise Glycerite Liquid Extract
Also known as: Anise, Aniseed, Anise Glycerite Liquid Extract, Pimpinella anisum
Overview
Pimpinella anisum, commonly known as Anise or Aniseed, is an annual herbaceous plant whose seeds are widely utilized for both medicinal and culinary purposes. Anise glycerite liquid extract is a concentrated, alcohol-free preparation that uses vegetable glycerin and purified water as solvents. This extraction method is designed to preserve water-soluble and some volatile constituents of the plant without the use of alcohol, making it suitable for individuals who wish to avoid alcohol. Traditionally, Anise has been employed to support digestive health, alleviate respiratory ailments, and as a flavoring agent. In contemporary applications, it is being explored for its potential in relieving menopausal symptoms, managing dysmenorrhea (menstrual pain), and exhibiting metabolic effects. While research on Anise is moderately mature with several clinical trials and pharmacological studies, specific systematic reviews focusing on glycerite extracts are limited. Most clinical data available are derived from studies on dried seed extracts or essential oils, rather than the glycerite form itself.
Benefits
Anise has demonstrated several evidence-based benefits, primarily in women's health and digestive support. A double-blind randomized controlled trial involving 72 postmenopausal women showed that anise extract capsules, taken three times daily for four weeks, significantly reduced the frequency and intensity of hot flashes (p < 0.05). This suggests a strong potential for anise in managing menopausal symptoms. For dysmenorrhea, a study with 180 young women indicated that a herbal capsule containing anise, alongside other herbs, was more effective in reducing menstrual pain than mefenamic acid, a common NSAID (p < 0.05). This highlights its utility as a natural alternative for menstrual pain relief. Furthermore, animal studies have shown that aniseed oil can increase glucose absorption in the rat jejunum by stimulating Na^+–K^+ ATPase activity, suggesting a potential role in metabolic modulation, although human data are currently lacking. In vitro studies have also revealed moderate cytotoxicity of star anise water extracts against liver cancer cell lines, with selectivity over normal cells, hinting at potential anticancer properties. However, the clinical relevance of these in vitro findings is yet to be determined.
How it works
Anise exerts its effects through several mechanisms. Its constituents, particularly volatile oils like anethole and estragole, are believed to stimulate Na^+–K^+ ATPase activity, which enhances glucose transport in intestinal cells. This mechanism may contribute to its potential metabolic modulating effects. These volatile compounds also possess antimicrobial, anti-inflammatory, and estrogenic-like activities, which are thought to contribute to the relief of symptoms associated with menopause and dysmenorrhea. The estrogenic-like activity may help balance hormonal fluctuations. The glycerite extraction method specifically preserves water-soluble phytochemicals and some volatile compounds without the use of alcohol, which can influence the bioavailability and overall therapeutic profile compared to alcohol-based tinctures.
Side effects
Anise is generally considered safe when consumed in traditional doses. Clinical trials and studies cited have not reported any significant adverse effects. In vitro studies have also shown no cytotoxicity in normal human cell lines at tested concentrations, indicating a favorable safety profile at the cellular level. There are no major drug interactions or contraindications extensively documented in high-quality clinical studies for anise. The alcohol-free glycerite form further reduces concerns related to alcohol sensitivity or contraindications, making it a suitable option for individuals who need to avoid alcohol due to health conditions, medication interactions, or personal preferences. While generally safe, as with any supplement, individuals with known allergies to plants in the Apiaceae family (e.g., celery, parsley, dill) should exercise caution due to potential cross-reactivity. Pregnant or breastfeeding women should consult a healthcare professional before use, as specific safety data for these populations are limited. Although rare, some individuals may experience mild gastrointestinal upset.
Dosage
The exact dosage for Anise Glycerite Liquid Extract has not been definitively established through clinical trials specifically using this form. Clinical research on menopausal symptoms utilized three capsules daily of dried anise extract for four weeks; however, direct glycerite dose equivalents are not yet determined. Glycerite extracts typically have a dry material to solvent ratio of 1:3, but standardized dosing requires further dedicated research to ensure consistent efficacy and safety. Generally, dosing should align with symptom management protocols, often involving daily administration for several weeks to observe benefits. It is crucial to follow the manufacturer's instructions on the product label, as concentrations can vary between brands. For specific health concerns, consulting a healthcare professional is recommended to determine an appropriate and safe dosage. Due to the lack of specific glycerite-based clinical trials, users should start with the lowest recommended dose and adjust as needed, while monitoring for effects.
FAQs
Is alcohol-free glycerite as effective as tinctures?
Glycerites preserve water-soluble and some volatile compounds but may differ in phytochemical profile from alcohol tinctures. Clinical efficacy equivalence is not fully established, so their effects might vary.
How soon can benefits be expected?
Clinical trials on anise extract report symptom improvement, particularly for hot flashes, within approximately four weeks of consistent use. Individual responses may vary.
Is it safe for long-term use?
Limited long-term data specifically on anise glycerite extracts exist. Traditional use suggests safety, but more extensive studies are needed to confirm long-term safety and efficacy. Consult a healthcare professional for prolonged use.

- https://pmc.ncbi.nlm.nih.gov/articles/PMC10035495/ – This double-blind RCT found that anise extract significantly reduced hot flash frequency and intensity in postmenopausal women over 4 weeks. It also noted that a herbal capsule containing anise reduced menstrual pain more effectively than mefenamic acid in young women. The study highlights anise's potential in women's health, though the dysmenorrhea finding was part of a combined herbal formula.
- https://pmc.ncbi.nlm.nih.gov/articles/PMC8361074/ – This in vitro study investigated the cytotoxicity of star anise water extract on liver cancer cell lines (Hep G-2) and normal cells (THLE2). It found moderate cytotoxicity against cancer cells while showing no toxicity to normal cells, suggesting a potential selective anticancer effect. However, the study emphasizes that these are in vitro findings and clinical relevance is unknown.
