Pregnancy consideration: Pregnant women should avoid chamomile, as it can cause contractions and may harm the fetus or infant.
Lactation: N/A
Pregnancy category:
Category A: well-controlled and Satisfactory studies show no risk to the fetus in the first or later trimester.
Category B: there was no evidence of risk to the fetus in animal studies, and there were not enough studies on pregnant women.
Category C: there was evidence of risk of adverse effects in animal reproduction studies, and no adequate evidence in human studies must take care of potential risks in pregnant women.
Category D: adequate data with sufficient evidence of human fetal risk from various platforms, but despite the potential risk, and used only in emergency cases for potential benefits.
Category X: Drugs listed in this category outweigh the risks over benefits. Hence these categories of drugs need to be avoided by pregnant women.
Category N: There is no data available for the drug under this category
Pharmacology:
chamomile (Matricaria chamomilla) is an herb used for centuries as a traditional medicine for various ailments. It is known for its anti-inflammatory, antioxidant, antispasmodic, and soothing properties. chamomile contains various bioactive compounds, including flavonoids, terpenoids, and phenolic compounds, contributing to its pharmacological effects.
Pharmacodynamics:
chamomile (Matricaria chamomilla) contains several bioactive compounds contributing to its pharmacological effects. Here are some of the pharmacodynamic effects of chamomile:
- Anti-inflammatory effects: chamomile contains flavonoids and terpenoids that have anti-inflammatory effects. These compounds inhibit the production of inflammatory cytokines and enzymes, which reduce inflammation and swelling.
- Antioxidant effects: chamomile contains phenolic compounds that act as antioxidants, protecting the body from oxidative stress caused by free radicals. These compounds scavenge free radicals and prevent damage to cellular components.
- Gastrointestinal effects: chamomile has been traditionally used to treat gastrointestinal disorders such as colic, diarrhea, and irritable bowel syndrome. Its antispasmodic properties help to relax smooth muscles in the gut, which may help reduce gastrointestinal disorder symptoms.
- Sedative effects: chamomile has a mild sedative effect and is commonly used to promote relaxation and sleep. Its sedative effects may be due to its ability to increase levels of the neurotransmitter GABA, which has a calming effect on the brain.
- Anti-cancer effects: chamomile contains apigenin, a flavonoid shown to have anti-cancer properties. Apigenin inhibits the growth of cancer cells and induces cell death in cancer cells.
- Immunomodulatory effects: chamomile has been shown to modulate the immune system, enhancing the production of specific immune cells and reducing the production of others.
Pharmacokinetics:
Absorption
chamomile is commonly consumed as an herbal tea, and the bioactive compounds in chamomile are readily absorbed from the gastrointestinal tract. However, the absorption of chamomile may be affected by factors such as the dose, formulation, and co-ingestion of other substances.
Distribution
The bioactive compounds in chamomile are distributed throughout the body via the bloodstream. However, the distribution of chamomile may be limited by factors such as the solubility and molecular weight of the bioactive compounds.
Metabolism
The bioactive compounds in chamomile are metabolized in the liver by enzymes such as cytochrome P450 enzymes. The primary metabolites of chamomile include apigenin and quercetin, which have been shown to have pharmacological effects.
Elimination and Excretion
