February. The cold bites. The light grows scarce.

You are here.
At the heart of winter.
The day breaks late, the sun hesitates, and the cold seeps everywhere—into the air, into the walls, sometimes even beneath the skin. February is not an easy season.
Nature is resting. Bodies are too.
And yet, this is when everything is decided. When light is missing and the cold settles in, taking care of yourself becomes an act of resistance.
A conscious choice.
An almost militant gesture.

🌱 Resisting winter, naturally
In this harsh climate, your body stands on the front line.
Lingering colds, deep fatigue, low spirits… winter puts our balance to the test.
Strengthening your immunity is not about fighting nature—it’s about reconnecting with it. The solution is not found in excess, but in a return to what truly matters.

🥬 Nourishing the body as we nourish the Earth
Your plate is your first refuge.
When everything outside looks grey, choose deep green:
✅Spinach
✅Kale
Rich in vitamin C, they support natural defenses, the way a forest protects its roots from frost.
And don’t forget white roots—quiet, but powerful:
✅Parsnips
✅Radishes
✅Onions
✅Cauliflower
These winter vegetables, firmly anchored in the soil, are rich in naturally protective compounds. They support the lungs and the gut, and remind us of a simple truth: what grows slowly builds lasting strength.

🌬️ Winter also attacks the skin
Your skin feels everything.
The outdoor cold.
Indoor heating.
Dry air.
Invisible toxins in enclosed spaces—sometimes up to five times more polluted than the outdoors.
In February, skin tightens, itches, becomes irritated. It loses its color the way trees have lost their leaves. But once again, nature has already provided an answer.

🌑 Nigella oil: one seed, an act of resistance
Used for centuries, black seed oil (Nigella) is a discreet yet powerful ally.
Antibacterial, soothing, and naturally anti‑inflammatory, it supports the skin through the seasons— especially when winter is at its harshest.

❄️ In autumn / winter, it can help to:
1. Soothe eczema
Cold air dries, irritates, inflames. Nigella oil helps calm redness and support a weakened skin barrier.
2. Relieve psoriasis
Artificial heat and dry air can worsen flare‑ups. Nigella is known for its calming effect on painful outbreaks and discomfort.
3. Rebalance acne‑prone skin
Even in winter, acne persists. Thanks to its soothing and antioxidant properties, black seed helps keep skin clearer and more even, despite seasonal stress.

🌍 Taking care of yourself is also an ecological act
In February, when everything seems frozen in place, every gesture matters.
Choosing simple foods.
Pure care.
Solutions that respect both body and planet. Caring for your health means refusing exhaustion, supporting your body the way we protect a fragile ecosystem. Winter is not an enemy. It is a trial. And you already have—within you and around you—the resources to get through it.

This year, love is found in simple gestures.

What if we talked about love differently?

Valentine’s Day often brings to mind red roses, expected words, quick gestures.
But what if, this year, we slowed down? What if love were not just a declaration, but an intention.
A conscious choice.
A moment given—to yourself or to those you love.
At BSO, we believe in a simpler, deeper kind of love. A love lived through everyday gestures, through the care we give to the body, through the time we choose to take.
🖤 Love is also about caring
Caring about what we put on our skin.
Caring for the body—its tensions, its balance.
Caring for ourselves, without excess.
BSO black seed oil embodies this philosophy:
✔️a pure, unrefined oil
✔️a respected origin
✔️an ancestral use
✔️an essential gesture
Used for centuries in body care, it has stood the test of time as a lasting wellness ritual.
🌙 A ritual rather than a gift
What if, this Valentine’s Day, you didn’t offer just another object, but a moment? A few drops of black seed oil warmed between the hands.
A slow massage.
A deep breath.
A moment of calm, alone or shared.
Massage with black seed oil works far beyond the surface of the skin.
Thanks to its dense, warm, and enveloping texture, it provides the perfect glide for a slow, deep massage. It allows precise work around the joints, tendons, and areas stressed by daily life.
Applied to the knees, shoulders, wrists, ankles, hips, hands, or lower back, black seed oil:
✔️relieves sensations of stiffness
✔️brings a feeling of suppleness
✔️improves perceived joint comfort
✔️warms and relaxes tense areas
✔️supports the body’s natural mobility
Regular massage with this oil encourages the release of deep‑seated tension, works on accumulated tightness, and creates a sense of overall relaxation.
The body loosens, movements become more fluid, posture softens.
The slow, deliberate gesture, combined with this rich oil, works into deeper tissues and creates a feeling of grounding and stability—almost down to the bones.
The skin is nourished, the joints loosen, the body finds its balance again.
Because love is not measured by how much it shines, but by how much it soothes.
🎁 Giving with intention
Offering BSO black seed oil means offering much more than a product.
It means offering:
✔️a ritual of care and presence
✔️a moment of relaxation and release
✔️a gesture that lasts over time A gift that simply says:
“I take care of you.”
🌿 Less pressure.
Fewer clichés.
More meaning.
This Valentine’s Day, choose an intention that lasts.

Confirmed outbreaks in Grand Est: isolation, temperature, hygiene.

Hello,

Cases of equine rhinopneumonia (HVE) have been confirmed in the Bas‑Rhin département. The disease is highly contagious among horses: it can cause fever, cough/nasal discharge, and sometimes more severe neurological forms. Goal: break chains of transmission with simple measures.

Do this right away
Take the temperature daily (before any outing/transport). ≥ 38.5 °C = immediate isolation + call the veterinarian.
Limit travel (shows, visits) and separate any horse that coughs or has a fever.
Strengthen hygiene: hands, dedicated equipment, stalls, transporters (cleaning + disinfection).
Check vaccination status depending on use (sport, breeding). Vaccination reduces viral shedding and disease severity.

And what about Haarlemer Oil for horses?

A traditional feed supplement (sulfur, pine essential oil, linseed oil) is sometimes used to support the airways and recovery. Important: it does not replace a veterinarian or vaccination. Managing an outbreak relies first on biosecurity + veterinary care + vaccination. Please discuss use with your veterinarian. [avef.fr], [ifce.fr]

Application/Dosage
Short course: 10 ml/day for 10–14 days, then 10 ml/week (½ dose for ponies).
Maintenance: 10 ml/week; sport horse: 10 ml 1–2×/week after exertion. Administration: mixed with feed or given by oral syringe.
When is it an emergency?

Persistent fever ≥ 38.5 °C, marked lethargy, purulent discharge, breathing difficulties, or neurological signs (incoordination, difficulty rising).

What is rhino pneumonia?

A highly contagious equine disease caused by herpesviruses (HVE‑1/HVE‑4). It can affect the respiratory tract, sometimes neurological, and cause abortions in breeding.

Is there a specific treatment?

There is no validated specific medication; care is based on isolation, supportive treatment, and biosecurity.

Is the situation in Grand Est confirmed?

Yes: HVE‑1 outbreaks were confirmed in Bas‑Rhin at the end of January, with quarantine measures and wide coverage in the local press.

Harsh Winter: How Haarlem Oil Supports the Horse —
From the Inside… and the Outside

When temperatures drop, horses feel it: joint stiffness, stable cough, dull coat, small skin issues. Haarlem Oil — a traditional blend of sulfur (16%), pine turpentine essence (≈ 80%) and linseed oil (≈ 4%) — provides highly bioavailable sulfur and can be used both orally and topically.

Quick Reminder: What Is Haarlem Oil?
A historical preparation (17th century) combining sulfur, pine essential oil, and linseed oil; the equine formulation is available in a 250 ml oral bottle.
Main goal: provide highly absorbable, non‑oxidized organic sulfur (“bioavailable sulfur”).
Why It’s Particularly Useful in Winter?

Respiratory Tract & Enclosed Stables

Traditional uses mention support for the respiratory system (cough, bronchitis); pine essential oil has historically been used for its expectorant and antiseptic properties.

Locomotor Comfort & Cold‑Weather Recovery
Haarlem Oil is a source of bioavailable sulfur, supporting the joints (winter stiffness, post‑work recovery).

Scientific side:

In horses, bioavailable sulfur has been associated with favorable modulation of muscle inflammatory genes after exercise (during a 30‑day period).

Equine nutrition reviews also highlight sulfur’s role in collagen, keratin, GAGs, oxidative stress management, and recovery.

Skin, Coat, Hooves

Sulfur is a component of keratin; in winter (humidity, blankets), the goal is a healthier coat and better-supported connective tissue.

"Detox" & Seasonal Metabolic Hygiene

Traditional usage includes post‑effort “detox” support and seasonal courses (spring/autumn)
— helpful in winter when turnout decreases and dust in stables increases.

Internal Use (Oral): Goals & Manufacturer‑Validated Dosages
To mix with feed or administer using an oral syringe.

External Use (Topical): When and How in Winter?

Manufacturer guidance: Haarlem Oil “may also be used externally”; local applications on superficial wounds (as an antiseptic) or on sore limbs.

Practical winter advice:

Apply a thin layer on clean, dry skin, away from mucous membranes, and protect from biting cold after application (avoid drafts on an oiled area).

Mud Fever (Pastern Dermatitis) — Adjunct Local Care

Objective: clean and dry the area, reduce moisture, and support the skin barrier.
Veterinary protocols prioritize hygiene + validated antiseptic/antimicrobial products.

Using Haarlem Oil:

After thorough cleansing and drying, apply a thin layer around non‑oozing lesions once daily for 3–5 days (traditional use).

Small Superficial Wounds / Scratches
Traditional use as an antiseptic rub to support healing of minor, well‑cleaned, non‑deep wounds.

Hair Regrowth (Thinned Areas After Skin Lesions)

Weeks 1–2: Clean & Stimulate

External application (on healthy or slightly damaged, non‑oozing skin):
Apply a thin layer of Haarlem Oil every other evening after grooming; no bandaging.
Daily hygiene: keep the area clean and dry; avoid blankets or prolonged rubbing on the spot.

Weeks 3–4: Consolidation & First Hair Regrowth

Reduce to 2–3 applications per week, provided the skin is clean and not irritated. Optional internal support: some manufacturers suggest 10 ml/week orally (bioavailable sulfur), useful in winter/box rest; not required for hair regrowth but may support overall recovery.

🐎If you’re looking for what really works… you’re in the right place.

Every day, owners write to us saying the same thing: “I’ve tried everything for mud fever… nothing works.” And that’s normal.

Most products on the market only address one aspect: hydration, texture, skin barrier…
Nothing designed to stop the bacteria, soothe inflammation, protect from moisture, and repair the skin—all at the same time.

Haarlem Oil is not a “general-purpose” balm.

It’s a complete treatment, formulated with natural ingredients and validated by independent veterinarians.

That’s why it can:

✔️Soothe inflammation within 48 hours
✔️Stop the bacteria that causes mud fever
✔️Protect the area from moisture and prevent recurrence
✔️Visibly speed up skin repair We chose effectiveness over convenience.

Natural ingredients, precise formulation.
Your horse deserves care that truly makes a difference.
Not just another product sitting in a cupboard.

🐴Discover why Haarlem Oil is the choice of the most demanding owners.

Haarlem Oil is a powerful ancient medicine drawn from a combination of sulphur with essential pine and linseed oils using a formula unexpectedly discovered about four centuries ago through Dutch alchemy in Haarlem, a city in Holland. The formula was found to be a highly effective solution for respiratory problems, weak nails and other ailments. Most prominently, it was recognized as a potent treatment for arthritis. Usage and popularity of the oil and its counter-arthritic properties soon spread across Europe. By 1924, the formula gained even more attention after French pharmacist Monsieur Thomas obtained a license to produce and market the product in France. He later passed down the lucrative business to his son-in-law, Dr. J. Lefevre, founder of the Lefevre Family Laboratory. This laboratory still makes the remarkable elixir to this day. Interestingly, the formula with which the oil was created over 400 years ago is the very same constitution of the oil today. Continuous studies conducted throughout the years on Haarlem Oil’s efficacy shed light on its bioavailability as well as purity. Bioavailability refers to how easily a nutrient or substance can make its way into your body after eating it.
