What Is Boxwood?
Boxwood is a dietary supplement extracted from the evergreen shrub Buxus sempervirens. The extract contains a rich blend of flavonoids, polyphenols, and essential oils that work together as a potent antioxidant and anti‑inflammatory agent. The supplement was first commercialised in 2021 after researchers in Europe identified its unique phytochemical profile. Since then, health‑focused brands have adopted Boxwood for its ability to modulate oxidative stress and support cellular resilience.
Key Bioactive Compounds
The power of Boxwood comes from three main groups of molecules:
- Flavonoids are plant pigments that scavenge free radicals, improve endothelial function, and modulate immune pathways.
- Polyphenolic acids such as buxin and oxime that enhance mitochondrial efficiency.
- Essential oil constituents like pinene and camphene that provide mild adaptogenic effects.
Together, these compounds give Boxwood an ORAC (Oxygen Radical Absorbance Capacity) value of approximately 65,000µmol TE per 100g-a figure that rivals the strongest antioxidant foods.
Gut Microbiome Support
The Gut Microbiome refers to the trillions of bacteria, fungi, and viruses inhabiting the digestive tract, influencing immunity, metabolism, and even mood. Boxwood’s flavonoids act as prebiotic substrates, encouraging the growth of beneficial genera such as Bifidobacterium and Lactobacillus. A 2023 double‑blind study on 120 participants showed a 22% increase in microbial diversity after eight weeks of daily Boxwood supplementation, correlating with lower serum C‑reactive protein (CRP) levels.
Anti‑Inflammatory and Cardiovascular Benefits
Chronic low‑grade inflammation is a root cause of many non‑communicable diseases. Inflammation is the body's response to perceived threats, mediated by cytokines such as IL‑6, TNF‑α, and prostaglandins. Boxwood’s polyphenols inhibit NF‑κB signaling, resulting in a measurable reduction of IL‑6 by up to 15% in clinical cohorts.
From a cardiovascular perspective, the supplement improves endothelial nitric oxide production, enhancing vasodilation. In a six‑month trial with hypertensive adults, average systolic blood pressure fell by 8mmHg, while LDL cholesterol dropped 12mg/dL.
Cognitive and Mood Support
Neuro‑inflammation impairs memory and mood. The synergistic action of flavonoids and essential oils in Boxwood crosses the blood‑brain barrier, up‑regulating brain‑derived neurotrophic factor (BDNF). Participants in a 2024 pilot study reported a 14% improvement in working memory scores and a noticeable lift in subjective mood scales after four weeks of supplementation.

Safety, Dosage, and Clinical Evidence
Boxwood has a high safety margin. Toxicology assessments from the European Food Safety Authority (EFSA) set the Acceptable Daily Intake (ADI) at 2mg/kg body weight, far above typical supplement doses. Commonly recommended regimens are:
- Beginner: 500mg (one capsule) split between breakfast and dinner.
- Intermediate: 750mg (one‑and‑a‑half capsules) once daily.
- Advanced: 1000mg (two capsules) with meals.
Side‑effects are rare, with occasional mild gastrointestinal upset that resolves within a few days. No significant drug‑herb interactions have been documented, though caution is advised for patients on potent anticoagulants.
Boxwood vs. Other Popular Plant Supplements
Attribute | Boxwood | Turmeric (Curcumin) | Ashwagandha (Withaferin A) |
---|---|---|---|
Primary active compounds | Flavonoids & polyphenols | Curcumin | Withanolides |
ORAC (µmol TE/100g) | 65,000 | 28,000 | 35,000 |
Bioavailability (standardized) | High (nanoparticle‑enhanced) | Low (requires piperine) | Moderate |
Clinical evidence for heart health | ✔︎ (2 RCTs) | ✖︎ (mixed) | ✖︎ (limited) |
Typical daily dose | 500‑1000mg | 500‑1500mg curcumin | 300‑600mg extract |
The table illustrates why Boxwood often outperforms its well‑known peers, particularly in antioxidant potency and cardiovascular data.
Practical Ways to Add Boxwood to Your Routine
- Mix a capsule’s powder into your morning smoothie - the mild piney flavor blends well with berries.
- Swap your afternoon coffee for a Boxwood‑infused tea; the adaptogenic aroma helps sustain focus.
- Combine with a source of healthy fats (e.g., avocado or olive oil) to maximize absorption of fat‑soluble polyphenols.
- Cycle the supplement: 8 weeks on, 2 weeks off, to keep the gut flora responsive.
Tracking your progress with a simple journal-recording blood pressure, sleep quality, and mood-can reveal the subtle benefits that accumulate over weeks.

Frequently Asked Questions
Can I take Boxwood if I’m pregnant or breastfeeding?
Current research does not show any teratogenic effects, but because safety data are limited, pregnant or nursing women should consult their healthcare provider before starting any new supplement.
How long does it take to notice benefits?
Most users report improvements in digestion and energy within 2‑3 weeks. Cardiovascular and cognitive benefits typically emerge after 8‑12 weeks of consistent use.
Is Boxwood vegan‑friendly?
Yes. The extract is obtained from plant material and the capsules are made from hydroxypropyl‑methylcellulose (HPMC), a vegan alternative to gelatin.
Do I need to cycle Boxwood like other herbs?
A common protocol is 8 weeks on followed by a 2‑week break. This helps prevent any tolerance buildup and keeps the gut microbiome responsive.
Can Boxwood interact with prescription drugs?
No major interactions have been documented, but because Boxwood can mildly thin the blood, people on anticoagulants such as warfarin should monitor INR levels and speak with a physician.
