What are herbal oral liquids–suspensions?

A herbal oral liquid (Herbal Oral Liquid) is a liquid-form product in which the actives are dissolved in water. Its strengths are being easy to drink, with adjustable taste–scent, and precise control of the active amount per dose, suited to users of all ages, from children to the elderly. Both formats can adjust taste–scent and active level flexibly to align with the law and the brand brief.

A herbal oral suspension (Herbal Oral Suspension) is a formula in which the active particles do not dissolve but are dispersed evenly in the formula medium, so it must be designed to address 3 main points:

Appropriate viscosity and flow (rheology)

Easy to drink, neither too heavy nor too thin.

Anti-sedimentation

Reduces separation during storage, keeping the formula's appearance consistent.

Good redispersibility after shaking

So the actives are consistent every time a dose is measured.

Formulas and ingredients: from extract to a stable, easy-to-drink formula

Base & Mouthfeel

Using purified water and tuning the feel to be easy to drink with humectants such as glycerin or sorbitol to balance viscosity, sweetness, and mouthfeel.

Suspension System

Using xanthan gum, CMC, and HPMC to control viscosity, reduce sedimentation, and provide good redispersibility after shaking, with consistent taste and color in every dose.

Wetting & Dispersion

Balancing aids so the particles disperse evenly in the medium, within the relevant safety and legal framework.

Preservation

Designed per the formula's pH/matrix, with a Preservative Efficacy Test (PET) plan to confirm the preservative system's effectiveness in the actual product.

Flavor & Sweetener

Using natural flavoring agents and appropriate sweeteners (such as stevia, sucralose) for easy drinking, and able to tune a "taste–scent signature" unique to the brand.

pH & Buffer

Using citric acid / sodium citrate to control the pH appropriately, helping stabilize the actives, taste, and color of the oral liquid.

Popular Botanicals

Such as Centella asiatica (gotu kola), Kaempferia parviflora (black galingale), Andrographis paniculata, Zingiber officinale (ginger), Curcuma longa (turmeric), and Phyllanthus emblica (Indian gooseberry), with the active level designed to comply with the law, for both OEM supplement / ODM supplement and export work (herbal liquid OEM Thailand).

Brand Differentiators

Creating sugar-free, alcohol-free, minimal-ingredient (clean-label concept) formulas, or brand-specific taste–scent tones, so contract manufacturing of herbal oral liquids clearly meets the B2B market.

Testing & Standards

To ensure herbal oral liquids/suspensions are safe, stable, and legally verifiable, we plan testing systematically as follows:

Physical & Rheological Profile

Testing viscosity, pH, sedimentation/separation tendency, redispersibility after shaking, particle size, as well as color and scent, for consistent quality in every dose.

Microbiological Quality & Safety

Testing microorganisms per the product category's criteria, for safe consumption.

Preservative Efficacy Test (PET)

Conducting a Preservative Efficacy Test (PET) within the actual formula of the liquid dietary supplement to confirm the preservative system works in practice.

Product Stability

Conducting a Stability Study under both accelerated and real-time conditions, following ICH-equivalent guidelines, to estimate the product life and appropriate storage conditions.

Active Ingredients And Contaminants

Confirming the active content per spec and testing heavy-metal/undesirable-substance limits to comply with the legal framework.

Production and quality control are carried out under GMP / HACCP / ISO standards by an OEM factory / ODM factory team with per-lot QC/QA and complete traceability documentation, ready for document submission and actual market launch.

Documentation and regulatory: get it right from the start, enter the market faster

Assessing the registration pathway

Helping analyze whether the project should go the liquid dietary supplement or traditional medicine route, with a timeline, required documents, and criteria to meet, so contract manufacturing of herbal oral liquids / suspensions proceeds smoothly.

Traditional medicine registration submission

Preparing a complete document set: Raw Material Specs, Finished Product Specs, Method of Analysis, efficacy documents per the legal framework, and the necessary Stability Test results.

Liquid dietary supplement notification submission

Preparing the formula and components, label, nutrition/warnings, and a responsible claim-communication approach to comply with requirements.

Label and packaging

Reviewing on-label text per FDA announcements, fill size, usage/storage details, and processing the food serial number/drug registration number once approved, so the product is ready for actual sale from the oral liquid contract manufacturer.

Quality document file

Preparing the Certificate of Analysis (COA), Specifications & MoA, per-lot QC/QA records, and a post-market quality monitoring plan, covering herbal oral liquid OEM / herbal suspension ODM work.
