NRI Botanical Lab · Stovehouse,

Botanicals and oil. Double maceration. 

Every bottle on this shelf started as plant material and carrier oil. Nothing else. The results are unctuous, concentrated, and unlike anything you will find anywhere else.

The process

Two full macerations. Same botanical. Stronger result.

Most infused oils run one cycle: herb into oil, heat, strain, done. These go through double maceration, meaning the strained oil is loaded back with a full charge of fresh botanical material and the process begins again. The oil you see in the bottle has extracted from that plant twice. The difference in color, viscosity, and potency is substantial.

Carrier oils are selected to match each botanical's character and intended use. Jojoba for botanicals that belong on the face and scalp. Camelina for its affinity with skin-repairing herbs. Sunflower for warm, all-purpose application. The carrier is part of the formula.

Double maceration is not standard practice in commercial botanical oil production. It takes twice as long and requires twice the plant material. The result is an oil with a depth of extraction that single-pass products cannot replicate.

Calendula infused oil
Calendula in camelina and sunflower. Warm, golden, and genuinely useful. The first oil we made and the one that never leaves the shelf.
Core collection

In stock year-round

Botanicals selected for their track record, sourced for quality, made here. These are on the shelf as long as the harvest holds.

Calendula
Camelina · Sunflower

Warm, golden, and genuinely useful. Body, face, dry skin, anything that needs soothing and will not wait.

Lavender
Jojoba

Not lavender essential oil. The whole flower, slowly drawn into jojoba. Quieter than the EO. More skin-compatible.

German Chamomile
Jojoba

Sensitive skin, reactive skin, skin that has been through something. This is what it is for.

Rose Petal
Jojoba

Fragrant, hydrating, made with actual rose petals. Face oil, décolleté, dry cuticles. Use it like you mean it.

Rosemary
Jojoba

Scalp oil first. Also a warming massage oil for tired legs and tight shoulders. The kind of thing you will use up and replace.

Lemon Balm
Sunflower

Bright, slightly herbaceous, lighter than most of the collection. Body oil, pulse points, anything you want to carry through the afternoon.

Hibiscus
Sunflower

Deep red-tinted, antioxidant-dense. The whole dried flower, extracted slowly. Face and body.

Plantain
Sunflower

The backyard herb with a long history of skin use. Cooling, soothing, and deeply practical. Body and spot application.

Vigne rouge red vine leaf from France
Vigne rouge from the Bordeaux region. Roughly 8 bottles from the entire batch. If you are here when it is available, that is the one to pick up.
Single origin

Named source. Named harvest. Limited to what the batch produced.

When it is gone, it is gone until the next one. Single-origin batches are sourced from specific international harvests, noted on each label.

Single Origin
Roman Chamomile
Jojoba
Batch 1/26 · Paris · Summer 2025

Sourced from Paris, summer harvest. Lighter and more floral than German chamomile. A different plant entirely, worth knowing.

Single Origin
Tilleul
Jojoba
Batch 1/26 · Loire Valley · Summer 2025

Linden blossom from the Loire Valley. Soft, slightly honeyed, calming without being sweet. One of the more quietly extraordinary botanicals in the collection.

Single Origin · Very Limited
Vigne Rouge
Camelina
Batch 1/8 · Bordeaux Region · Summer 2025

Red vine leaf from France. Roughly 8 bottles from the entire batch. Antioxidant-dense, slightly astringent. If you are here when it is available, that is the one to pick up.

Before you buy

A few things worth knowing.

These are infused oils, not essential oils.

Essential oils are steam-distilled concentrates. Infused oils are carrier oils that have absorbed botanical compounds through slow maceration. They are gentler, more skin-compatible, and intended for direct application. No dilution required.

What does double maceration actually mean?

The oil goes through two full rounds of botanical extraction with fresh plant material each time. Most products on the market are single-pass. The difference is visible in the color and in how the oil performs on skin.

Shelf life and storage.

12 months from the batch date on the label. Store away from heat and direct light. The cobalt glass is doing work. Let it do it.

Where do the botanicals come from?

Domestic botanicals are sourced from regional growers, and direct farm relationships. Single-origin batches are sourced from specific international harvests, noted on each label.
