“I’ve got a stomach bug…”
Behind these few words lies a short but intense and unpleasant series of symptoms. Diarrhea, vomiting, fever, and body aches are typical signs of gastroenteritis. Most often of viral origin, it requires appropriate care to help reduce the infection, limit fluid loss, and soothe intestinal discomfort.
Five essential oils, known for their anti-infectious, antispasmodic, and anti-nausea properties, can help provide relief and support recovery of energy and comfort.
Symptoms of Gastroenteritis
Gastroenteritis is an inflammation of the stomach and intestines, most commonly manifested by acute diarrhea. Diarrhea itself is a symptom; the underlying cause may vary and can include indigestion, bacterial food poisoning, parasites, viruses, or excessive sugar intake.
Viral Gastroenteritis: Symptoms
Most cases of gastroenteritis are viral in origin. Transmission occurs orally, and the severity of the condition largely depends on the extent of fluid loss.
Fluid loss through diarrhea and vomiting can be particularly concerning in young children, with a significant risk of dehydration.
The most severe cases require urgent medical care.
Common symptoms include:
- Sudden onset, with very frequent urges to use the bathroom and loose or watery stools
- Abdominal cramps, nausea, and sometimes vomiting
- Occasionally fever and muscle aches
- Recovery usually within 3 to 5 days
Viral Gastroenteritis: What to Do
In adults and adolescents, dietary and hygiene measures combined with the use of essential oils can help support a faster recovery.
- Favor carrot soup, rice water, bananas, and grated raw apples, taken in small, frequent portions if needed, to help normalize stools
- Avoid dairy products and gluten
- Supplement with probiotics to support immune defenses
- When traveling to high-risk regions, avoid raw foods not cleaned by yourself and drink only bottled water or water treated with purification tablets designed for this purpose
Supporting Gastroenteritis with Essential Oils
Anti-infectious and Anti-fermentation Essential Oils: Cinnamon and Bay Laurel
Cinnamon Essential Oils
Cinnamon trees are large members of the Lauraceae family, native to Asia. Their bark has been used as a spice for thousands of years for its strengthening, purifying, and warming properties. Both bark and leaves are rich in aromatic compounds and yield essential oils with well-established anti-infectious properties, particularly effective on the digestive and urinary systems.
Three cinnamon essential oils are commonly used:
- Ceylon Cinnamon Bark Essential Oil (Cinnamomum zeylanicum, bark)
- Chinese Cinnamon Leaf Essential Oil (Cinnamomum cassia, leaf)
Both are rich in cinnamaldehyde, a powerful broad-spectrum antibacterial molecule. They also possess antiviral and antifungal properties and act specifically on the intestinal tract, making them suitable for various types of diarrhea.
- Ceylon Cinnamon Leaf Essential Oil (Cinnamomum zeylanicum, leaf)
Very rich in eugenol (up to 70%), with clove-like, spicy, and woody notes. It is also useful in intestinal and urinary infections, although it is less well known.
Bay Laurel Essential Oil
- Bay Laurel Essential Oil (Laurus nobilis)
A tree native to Mediterranean regions, whose leaves are traditionally used in cooking. Its essential oil offers multiple properties and is particularly effective at limiting gastrointestinal fermentation. It also helps support purification and balance of the gut microbiota.

Antispasmodic Essential Oils: Tropical Basil and Tarragon
- Tropical Basil Essential Oil (Ocimum basilicum)
- Tarragon Essential Oil (Artemisia dracunculus)
These two essential oils are considered the primary antispasmodics in aromatherapy. Rich in estragole, their neuromuscular antispasmodic action is well established. Used occasionally and appropriately, they help relieve digestive spasms, easing abdominal cramps and sometimes nausea.
Anti-Nausea Essential Oils: Lemon and Peppermint
- Lemon Essential Oil (Citrus limonum)
- Peppermint Essential Oil (Mentha × piperita)
Their anti-nausea properties—gentle for lemon, powerful for peppermint—are especially appreciated in cases of gastroenteritis accompanied by vomiting.
Lemon essential oil is also a mild liver-supportive and general tonic oil. With no particular toxicity, it can even be used in children.
Peppermint essential oil shares similar liver-supportive properties but is significantly more potent and requires strict precautions for safe use.
Simple Aromatherapy Practices for Adults
Gastroenteritis: Simple Oral Use
Bay Laurel Essential Oil
- 1-2 drops on a neutral tablet, 3 times per day for a few days
OR
Ceylon Cinnamon Bark Essential Oil (caution: strongly irritating / dermocaustic)

This can be done 2 to 3 times per day for 2 to 3 days.
Encapsulation is essential to avoid any risk of burns to the mouth or throat. Dermocaustic essential oils should never be applied on the skin, as they may cause skin burns.
