Mechanism of Action
The primary mechanism of action of Andrographis paniculata is through its bioactive component, andrographolide, which exhibits anti-inflammatory, antiviral, and immunomodulatory effects. Andrographolide inhibits pro-inflammatory cytokines and mediators such as TNF-α, IL-6, and NF-κB. It also enhances immune responses by stimulating the production of antibodies and activating white blood cells to fight infections. The antiviral activity is thought to result from the inhibition of viral replication in infected cells.
How Long Does It Take to Work?
Effects can vary depending on the condition being treated. For upper respiratory tract infections, relief of symptoms such as sore throat and nasal congestion is typically noticed within 2-3 days of use. For chronic inflammatory conditions, it may take 1-2 weeks of consistent use to observe benefits.
Absorption
Andrographolide, the main active compound, is absorbed through the gastrointestinal tract. Bioavailability is moderate due to its lipophilic nature, and the peak plasma concentration is typically reached within 1-2 hours after oral administration.
Route of Elimination
Andrographis paniculata and its metabolites are primarily excreted through the liver and kidneys. It undergoes hepatic metabolism and is eliminated in the bile and urine.
Dosage
