Medicinal and Aromatic Plants Course

Lesson 1 • Plant Morphology and Identification

Covers vegetative and reproductive structures used to distinguish medicinal species. Connects morphological features to correct field identification.

Lesson 2 • Plant Taxonomy and Botanical Classification

Introduces binomial nomenclature and major plant families relevant to aromatics and medicine. Enables accurate identification and professional communication.

Lesson 3 • Introduction to Phytochemistry

Surveys primary and secondary metabolite classes found in medicinal plants. Links chemical families to therapeutic and aromatic properties.

Lesson 4 • History and Cultural Context of Plant Use

Traces medicinal plant use from ancient civilisations to modern phytotherapy. Establishes why historical knowledge informs contemporary practice.

Lesson 1 • Voucher Specimens and Documentation

Covers collection, pressing, and labelling of voucher specimens for professional records. Ensures traceability and supports quality assurance in plant-based work.

Lesson 2 • Digital and Technology-Aided Identification

Introduces image-recognition apps, digital herbaria, and GPS-based plant databases. Positions technology as a supplement to, not replacement for, classical skills.

Lesson 3 • Field Identification Techniques

Teaches systematic observation protocols for identifying plants in natural habitats. Builds confidence in distinguishing medicinal species from toxic lookalikes.

Lesson 4 • Using Botanical Keys and References

Guides students through dichotomous keys and authoritative botanical references. Develops independent identification capability without reliance on single sources.

Lesson 1 • Propagation Methods

Covers seed germination, vegetative propagation, and tissue culture for medicinal species. Enables selection of the most efficient method per species.

Lesson 2 • Organic and Integrated Crop Management

Presents organic fertilisation, pest management, and crop rotation strategies. Ensures chemical residue-free plant material suitable for medicinal use.

Lesson 3 • Soil, Climate, and Site Requirements

Analyses soil chemistry, drainage, and microclimate factors that determine plant quality. Connects site selection to yield and phytochemical concentration.

Lesson 4 • Harvesting Timing and Techniques

Establishes optimal harvest windows based on phenological stage and active compound peaks. Directly impacts potency and shelf life of the final product.

Lesson 1 • Good Agricultural and Collection Practices

Applies internationally recognised GACP frameworks to farm and wild-harvest operations. Ensures traceability from field to finished product.

Lesson 2 • Storage Conditions and Packaging

Defines temperature, humidity, light, and oxygen controls for long-term storage. Prevents degradation of volatile and heat-sensitive compounds.

Lesson 3 • Laboratory Quality Testing Methods

Introduces thin-layer chromatography, HPLC, and microbial testing for plant material. Connects lab results to safety and efficacy claims.

Lesson 4 • Drying and Dehydration Methods

Compares air drying, oven drying, freeze drying, and solar drying for different plant parts. Matches method to compound stability requirements.

Lesson 1 • GC-MS Analysis and Oil Authentication

Teaches GC-MS chromatogram interpretation and adulteration detection for essential oils. Enables practitioners to verify oil identity and purity claims.

Lesson 2 • Cold Press and Solvent Extraction

Explains cold pressing for citrus oils and solvent extraction for absolutes and concretes. Addresses solvent residue concerns and quality implications.

Lesson 3 • Principles of Essential Oil Chemistry

Reviews terpene classes, functional groups, and volatility that define essential oil composition. Provides the chemical foundation for extraction and quality decisions.

Lesson 4 • Steam and Hydro-Distillation Techniques

Covers apparatus setup, operating parameters, and yield optimisation for distillation methods. Identifies which plant materials suit each distillation approach.

Lesson 1 • Aqueous Preparations: Infusions and Decoctions

Covers water-based extraction ratios, temperature, and time for different plant parts. Establishes baseline formulation skills applicable to all preparation types.

Lesson 2 • Formulation Documentation and Stability Testing

Establishes batch records, SOPs, and accelerated stability protocols for herbal products. Ensures reproducibility and regulatory readiness of formulations.

Lesson 3 • Standardised Extracts and Dry Powders

Introduces spray drying, lyophilisation, and marker-compound standardisation. Bridges artisan formulation with pharmaceutical-grade production standards.

Lesson 4 • Topical Preparations: Oils, Salves, and Creams

Formulates infused oils, beeswax salves, and emulsified creams for external application. Connects carrier selection to skin absorption and stability.

Lesson 1 • Herb-Drug Interactions and Contraindications

Identifies pharmacokinetic and pharmacodynamic herb-drug interactions and contraindicated populations. Enables safe integration of herbal and conventional therapies.

Lesson 2 • Evaluating Phytotherapy Research

Teaches critical appraisal of clinical trials, systematic reviews, and monographs for herbal medicine. Distinguishes high-quality evidence from anecdotal claims.

Lesson 3 • Dosage Principles and Administration Routes

Establishes dose-response relationships, therapeutic windows, and route-specific bioavailability. Prevents under-dosing and toxicity in professional practice.

Lesson 4 • Designing Client Wellness Protocols

Guides intake assessment, protocol design, and follow-up monitoring for individual clients. Integrates evidence, safety, and client-centred goals into actionable plans.

Lesson 1 • Product Dossier and Safety Assessment

Builds a product dossier including safety data, efficacy evidence, and stability results. Prepares students for regulatory submission and third-party audits.

Lesson 2 • Labelling Requirements and Claims

Covers mandatory label elements, permitted health claims, and prohibited disease claims. Prevents costly regulatory violations at the point of sale.

Lesson 3 • Good Manufacturing Practices for Botanicals

Applies GMP principles to botanical product facilities, equipment, and personnel. Ensures product safety, identity, strength, and purity at commercial scale.

Lesson 4 • Regulatory Categories for Plant Products

Distinguishes dietary supplements, cosmetics, traditional medicines, and food-grade plant products by regulatory definition. Determines compliance pathway before product development begins.
