Bitter Sweet began with a shared vision between Natch and Andrea Sokol: to create a mouthwash that supports overall wellbeing, honours the body’s natural abilities, and stays rooted in nature.
A formula that channels nature’s quiet strength into daily oral comfort.
This one-of-a-kind mouthwash tab emerged from a deep creative collaboration with Andrea Sokol – author, health advocate and founder of Ohlala & Solala – who inspired us to value the extraordinary properties of Cistus, the Mediterranean “super-plant”.
What once seemed impossible became reality: transforming the intense, herbaceous character of Cistus into a microbiome-friendly, modern and refreshing mouthwash experience.
We experimented, refined, tasted, adjusted – until we found the perfect bittersweet harmony between Cistus, Grapefruit and Postbiotics.
The result is a one of a kind innovation:
a chewable, bioactive mouthwash tab that unites botanical tradition with modern microbiome science.
A formula created with intention.
Crafted with courage.
And designed to support your oral wellbeing in an entirely new way.

Powered by Cistus. Crafted for natural microbiome balance.
Cistus – one of the Mediterranean’s most remarkable botanicals – sits at the heart of this formula.
Known for its natural astringency and polyphenol richness – traditionally valued in oral care – Cistus brings a sense of purity, wholeness and soothing care to your daily ritual.
Blended with Grapefruit oils and Postbiotics, Bitter Sweet becomes an entirely new kind of mouthwash: bioactive, balancing, and beautifully bittersweet.
Powered by Double Mint & Bergamot. Crafted for instant freshness.
Mint – in its most powerful form – sits at the heart of this formula.
A bold fusion of peppermint and spearmint delivers immediate clarity and long-lasting freshness, while bergamot adds a crisp citrus lift that feels clean, modern and energising.
Blended with Postbiotics, Zinc and Micro-Hydroxyapatite, Boombastic becomes a new kind of mouthwash:
fast-acting, alcohol-free, and designed to support daily oral hygiene – without water, without compromise.
To understand how to maintain a balanced oral microbiome, let’s look at three key players
🔹 Prebiotics = Food for beneficial bacteria (e.g., fiber from vegetables & whole grains)
🔹 Probiotics = Live, beneficial bacteria (e.g., found in yogurt, fermented foods, supplements)
🔹 Postbiotics = Compounds extracted from probiotics during fermentation that support gut and oral health, boost the immune system, and help reduce inflammation. Unlike probiotics, these beneficial substances are non-living and more stable.
In the mouth, postbiotics help regulate harmful bacteria, strengthen the natural protective barrier of the gums, and support long-term oral health. They may help reduce gum irritation, protect against plaque buildup, and promote a healthier oral environment.
Postbiotics help:
✅ Help maintain healthy teeth and gums.
✅ Promotes a healthy oral microbiome.
✅ Supports the gums’ protective barrier.
This innovative technology delivers the benefits of probiotics – without the downsides of instability.
