What is Chickweed?

Chickweed is a small herbaceous plant found growing throughout North America and Europe. It has naturalized on nearly every continent and thrives in colder climates.

Although there is not much modern research involving chickweed, it has a rich history in traditional medicine.

Chickweed was used internally for lung infections and irritations, and topically for skin conditions like eczema and psoriasis.

The herb was mainly used as a succas, or consumed whole in fresh form.

 

How Is Chickweed Used?

Chickweed is used internally for lung conditions, including asthma, chronic bronchitis, or asthma. Topically, it's made into creams and salves for skin irritations. This can include psoriasis, eczema, skin ulcers, or rashes. It's also consumed as a food in many Northern climates where it grows naturally.

Botanical Information

Chickweed is known for its creeping nature, and ability to grow in very cold weather. It's even been found growing underneath the snow in mountainous regions of North America.

Chickweed is a member of the Caryophyllaceae family, which contains as many as 2625 species distributed into 81 genera.

The Stellaria genera itself contains between 90 and 120 different species.

 

Clinical Applications Of Chickweed

There is little research on chickweed — however, it was shown to have high levels of carotenoids and a handful of antibacterial compounds like caryophyllene, menthol, and linalool.

Chickweed also contains saponins — which are thought to have a soothing effect on the skin. This is likely the mechanisms behind chickweeds popularity as an ointment for skin inflammation and infection.

For this application, chickweed is generally used as a fresh succas or made into salves, oils, and creams.

The traditional use for lung conditions is thought to be due to the saponin content, which is well known to have mucus membrane irritant effects, promoting the excretion of mucus.

+ Contraindications

  • Skin irritation and allergies may occur from topical application.

What is Lavender?

Lavender is one of the most famous herbs known to man. It's cultivated on a massive scale throughout Europe and North America and is a popular flavoring and aromatic agent for household products.

Medicinally lavender is best known for its ability to promote sleep. It's often sold as aromatherapy, in salves and creams, and incense for this purpose. Lavender is also great for internal use, where it interacts with the GABA system to produce relaxation and sleep.

Lavender essential oil can be used as a topical agent for insect bites, rashes, and infection.

Lavender is mainly used in topical applications for rashes, skin irritations, mild infections, sunburn, and insect bites. Internally it's mainly used for anxiety-related conditions, GIT inflammation and discomfort, and insomnia.

Botanical Information

Lavender is a member of the mint family (Lamiaceae). In the genus Lavandula, there are approximately 47 species — most of which are perennials, or small shrubs.

There are a number of lavenders used medicinally

  • Lavandula angustifolia (English Lavender)

  • Lavandula stoechas (French Lavender)

  • Lavendula dentata (Spanish Lavender)

This list is disputed by many taxonomists, suggesting that French lavender may be Lavandula stoechas or Lavandula dentata, and that Spanish lavender could be either Lavandula dentata, or Lavandula lanata, or Lavandula dentata.

 

Clinical Applications Of Lavender:

Lavender is useful topically for female conditions including dysmenorrhoea and PMS due to its antispasmodic and analgesic effects. It's also useful topically for its anti-fungal and antibacterial effects. Internally lavender can be used for gastrointestinal complaints, including bloating, flatulence, and colic.

Lavender is a reliable nervine for its GABAergic activity. Additionally it has been shown to reverse the stimulating effects induced by caffeine, and inhibits acetylcholine release.

 

Cautions:

Lavender has been proven to be a very safe herb with a low incidence of adverse effects.

Avoid use with pharmaceutical sedatives due to the possibility of agonistic synergy.
