Description:Herbal Mouth Freshener Patent Application - Complete Specification
1. TITLE OF THE INVENTION
Herbal Mouth Freshener Composition for Oral Hygiene and Teeth Cleaning
2. FIELD OF THE INVENTION
The present invention relates to oral care, specifically to a herbal mouth freshener formulation which not only provides long-lasting freshness but also supports teeth cleaning, plaque reduction, and gum health. The invention further relates to its formulation in various dosage forms such as granules, lozenges, and chewing gum.
3. BACKGROUND OF THE INVENTION
Oral hygiene remains a critical health concern worldwide. In India, a large population consumes tobacco-based mouth fresheners such as gutka, supari, and pan masala. These products are linked with severe health risks, including tooth discoloration, plaque formation, periodontal diseases, and oral cancer.
Conventional herbal or synthetic mouth fresheners address bad breath only but fail to offer functional oral cleaning. Some products use fennel, cardamom, or clove for taste but lack ingredients with antibacterial, plaque-reducing, and stain-removing properties.
Thus, there exists a need for a novel, safe, ayurvedic herbal composition that offers dual benefits: (1) freshening breath and (2) actively contributing to oral hygiene and teeth cleaning.
4. STATEMENT REGARDING BIOLOGICAL RESOURCES
The present invention makes use of Indian biological resources including Miswak (Salvadora persica), Neem (Azadirachta indica), Tulsi (Ocimum sanctum), Clove (Syzygium aromaticum), Cardamom (Elettaria cardamomum), Mint (Mentha species), and Fennel (Foeniculum vulgare).
As required under Section 6 of the Biological Diversity Act, 2002, approval from the National Biodiversity Authority (NBA) will be duly obtained and submitted prior to the grant of this patent.
5. SOURCE AND GEOGRAPHICAL ORIGIN
The plant materials used in the invention were sourced from local Indian suppliers/markets in [City, State]. Miswak (Salvadora persica), Neem (Azadirachta indica), Tulsi (Ocimum sanctum), Clove (Syzygium aromaticum), Cardamom (Elettaria cardamomum), Mint (Mentha spp.), and Fennel (Foeniculum vulgare) are of Indian origin. The applicant undertakes to obtain approval from the National Biodiversity Authority (NBA) as required under Section 6 of the Biological Diversity Act, 2002, prior to the grant of the patent.
