Chamomile

Matricaria chamomilla

Key Facts

Scientific Name
Matricaria chamomilla [2]
Plant Family
Asteraceae [2]
Origin
Macaronesia, North Africa, and temperate Eurasia to Indo-China [2]
Primary Use
Tea use and preliminary clinical research [1]

Overview

This profile covers German chamomile, an annual herb used for tea. Roman chamomile is a different plant; findings should not be assumed to apply equally to both. [1] [2]

Traditional Uses

Chamomile appears in ancient medical traditions. Its longstanding use does not by itself demonstrate clinical effectiveness. [1]

Preparation Matters

The cited clinical summary covers chamomile preparations rather than isolated compounds. Studies of multi-herb products cannot establish chamomile’s individual contribution. [1]

What the Evidence Says

Reliable evidence is insufficient to determine chamomile’s usefulness for most conditions. Preliminary supplement studies suggest possible benefit for generalized anxiety disorder, but evidence for insomnia is very limited; one study in a review found no benefit. [1]

Safety & Side Effects

Tea and food amounts are generally considered likely safe, but allergic reactions, including severe reactions, can occur, especially with related-plant allergies. Interactions with warfarin and some liver-metabolized medicines have been reported; interactions with sedatives are possible. Pregnancy and breastfeeding safety is uncertain. Seek clinical advice with medicines or estrogen-sensitive conditions. [1]

When to See a Doctor

Seek immediate medical attention if you experience:

  • Severe allergic reactions (difficulty breathing, swelling of face or throat, severe rash)
  • Chest pain or irregular heartbeat
  • Severe digestive issues (persistent vomiting, bloody stools)
  • Severe headache or dizziness
  • Any symptoms that worsen or do not improve

Always consult a healthcare professional before using herbal supplements if you:

  • Are pregnant, nursing, or planning to become pregnant
  • Are taking prescription medications
  • Have a chronic health condition
  • Are scheduled for surgery
  • Are giving herbs to children

Growing Notes

German chamomile prefers full sun and well-drained soil. Avoid heavy, wet soil. It is grown from seed and does not transplant readily. [2]
