Halitosis, commonly referred to as oral malodor, is a prevalent condition affecting a significant portion of the global population and is often associated with social embarrassment, reduced self-esteem, and impaired quality of life. The condition primarily arises due to the production of volatile sulfur compounds (VSCs), such as hydrogen sulfide, methyl mercaptan, and dimethyl sulfide, by anaerobic microorganisms residing in the oral cavity, particularly on the dorsum of the tongue and within periodontal pockets. In addition to intraoral factors, extraoral causes such as respiratory tract infections, gastrointestinal disorders, and systemic diseases may also contribute to halitosis. Conventional therapeutic approaches, including mechanical cleaning methods and chemical agents like mouthwashes, sprays, and lozenges, provide only temporary relief and are often associated with limitations such as short duration of action, unpleasant taste, mucosal irritation, and reduced patient compliance. These drawbacks highlight the need for innovative, effective, and patient-friendly delivery systems. Mouth dissolving strips (MDS) have emerged as a novel oral drug delivery platform characterized by rapid disintegration, ease of administration without water, precise dosing, and improved bioavailability. These thin polymeric films dissolve quickly upon contact with saliva, ensuring immediate release of active constituents directly at the site of action, thereby offering a rapid onset of therapeutic effect. (1,3,9) The incorporation of polyherbal ingredients into mouth dissolving strips presents a promising approach due to their synergistic antimicrobial, antioxidant, anti-inflammatory, and deodorizing properties. Such formulations not only target the underlying microbial etiology of halitosis but also help in neutralizing malodorous compounds and maintaining overall oral hygiene. Recent advancements in formulation technologies have enabled the development of stable, flexible, and palatable polyherbal mouth dissolving strips with enhanced therapeutic efficacy and patient acceptability. Additionally, emerging strategies such as nanocarrier incorporation, mucoadhesive systems, and sustained-release formulations are further expanding the potential of this drug delivery system in oral healthcare. This review aims to comprehensively discuss the etiology, pathophysiology, and current management strategies of halitosis, while emphasizing recent developments and future prospects of polyherbal mouth dissolving strips as an effective and innovative approach for its management.

Halitosis, commonly known as oral malodor, is a widespread condition characterized by an unpleasant odor originating from the oral cavity. It affects individuals of all age groups and can significantly impact social interactions, confidence, and overall quality of life. The primary cause of halitosis is the production of volatile sulfur compounds (VSCs) such as hydrogen sulfide and methyl mercaptan by anaerobic bacteria present on the tongue surface and in periodontal pockets. (11) Poor oral hygiene, tongue coating, dental caries, and periodontal diseases are the major intraoral contributors, while systemic conditions like respiratory infections and gastrointestinal disorders may also play a role. The condition is often persistent and requires effective management strategies targeting both symptoms and underlying causes. Conventional treatment methods such as mouthwashes, chewing gums, and sprays provide only temporary relief and may be associated with side effects like altered taste and mucosal irritation. Therefore, there is a growing need for innovative, fast-acting, and patient-friendly drug delivery systems. Mouth dissolving strips have emerged as a promising approach in oral care due to their rapid disintegration, ease of administration without water, and ability to deliver active ingredients directly into the oral cavity. These thin films enhance patient compliance and provide immediate breath freshening effects. When combined with polyherbal ingredients, they offer additional advantages such as natural antimicrobial activity, reduced toxicity, and improved therapeutic efficacy.Thus, polyherbal mouth dissolving strips represent a novel and effective strategy for the management of halitosis, addressing both the microbial cause and the need for convenient drug delivery.
Etiology and Pathophysiology of Halitosis
Etiology of Halitosis
Halitosis (oral malodor) is a multifactorial condition that originates from both intraoral and extraoral sources. Approximately 85–90% of cases are intraoral in origin, primarily due to microbial activity.
Intraoral Causes (Primary Halitosis)
a) Tongue Coating (Major Cause)
b) Periodontal Diseases
c) Dental Conditions
d) Reduced Salivary Flow (Xerostomia)
Extraoral Causes (Secondary Halitosis)
a) Respiratory Tract Disorders
b) Gastrointestinal Disorders
c) Systemic Conditions
d) Dietary and Lifestyle Factors
Pathophysiology of Halitosis
The pathophysiology of halitosis is primarily associated with the production of volatile sulfur compounds (VSCs) by oral microorganisms. (11)

Mouth Dissolving Strips (MDS) as Drug Delivery System
Mouth dissolving strips are thin, flexible films that dissolve rapidly when placed on the tongue without the need for water.
Advantages
Mechanism
The strip hydrates in saliva → disintegrates → releases active ingredients → acts locally in the oral cavity.

Recent Advances and Future Perspectives
Polyherbal mouth dissolving strips represent a promising advancement in oral healthcare due to their rapid action, natural composition, and improved patient acceptability.
RESULT
Based on available literature, polyherbal mouth dissolving strips are expected to show effective management of halitosis by reducing volatile sulfur compounds (VSCs) and inhibiting odor-causing oral bacteria. The strips provide rapid disintegration, immediate drug release, and improved patient compliance. The polyherbal approach enhances antimicrobial and deodorizing effects with minimal side effects. Overall, this drug delivery system demonstrates promising potential for safe, convenient, and effective control of oral malodor. (11)
CONCLUSION
Polyherbal mouth dissolving strips represent a promising and innovative approach for the management of halitosis. They offer rapid action, improved patient compliance, and effective reduction of odor-causing bacteria. The combination of herbal ingredients provides a safe and multifunctional therapeutic effect. Overall, this system has strong potential as an efficient, convenient, and patient-friendly alternative for oral malodor management.
DISCUSSION
The reviewed literature suggests that polyherbal mouth dissolving strips are an effective approach for managing halitosis by targeting its primary cause—odor-producing oral bacteria. The rapid disintegration and local drug delivery of the strips ensure quick action and improved patient compliance compared to conventional methods. The inclusion of multiple herbal components provides synergistic antimicrobial and deodorizing effects while minimizing side effects. However, most findings are based on preliminary studies, and further clinical validation is required to confirm long-term efficacy, safety, and stability of these formulations.
