2. Methods for Assessing Acute Oral Toxicity

Acute oral toxicity refers to the adverse effects that occur following the ingestion of a single dose of a substance. It is a critical aspect of safety assessment for plant extracts, which are increasingly being used in various medicinal and therapeutic applications. Several methods are employed to evaluate the acute oral toxicity of plant extracts, ensuring the safety and efficacy of these natural products.

2.1 In Vivo Testing

In vivo testing involves the administration of plant extracts to live animals to observe their toxicological effects. This method is considered the gold standard for assessing acute oral toxicity due to its ability to mimic human exposure conditions.

- 2.1.1 Rodent Models: Rodents, such as mice and rats, are commonly used due to their ease of handling, short life span, and genetic similarity to humans. They are often the first step in toxicity testing.
- 2.1.2 Dose Determination: The dose of the plant extract is determined based on preliminary studies or historical data. It is crucial to establish a range of doses to identify the lethal dose 50 (LD50), which is the dose that causes death in 50% of the test animals.
- 2.1.3 Observation Period: After administration, animals are observed for signs of toxicity, including behavioral changes, physiological responses, and mortality. Observations are made over a specified period, typically 14 days.

2.2 In Vitro Testing

In vitro testing uses isolated cells, tissues, or cell lines to study the effects of plant extracts. This method is advantageous for its ability to control experimental conditions and reduce the use of animals.

- 2.2.1 Cytotoxicity Assays: These assays measure the ability of plant extracts to kill cells, providing an initial assessment of toxicity.
