https://www.britannica.com/plant/Asteraceae More info on Asteraceae
One of the most widely used medicinal plants in the world! Used for thousands of years as a styptic (plant that stops bleeding) - Achilles was said to save the lives of many soldiers by applying the plant to their wounds. Alkaloids within the plant reduce clotting time and may suppress menstruation. It has sedative, pain killing, antiseptic, anti inflammatory, and antispasmodic constituents that may help with menstrual cramps. It is often used in washes, salves and poultices for just about everything, and the tea can be used as a tonic for colds and fevers because it stimulates sweating and lowers blood pressure.
It can also be used in perfume and bath powder when dried. Fresh leaves are effective (but temporary) as a bug repellent, they are fragrant, and yarrow tea is reported as an excellent hair rinse.

Achillea millefolium
Yarrow- Identifying Features
Form:
Height and Spread - 60 - 80 cm (2’) x 1 m (3.5’) PLUS
Corymb - like a cyme and umbel mixed - joined to the base like a cyme, but with a flat top.
Colours can be bright or pastels depending on the blend purchased. Few people plant the species - it’s just too invasive. More often cultivars like ‘Terracotta’ or ‘Paprika’ (yellow/orange and red) or “summer Pastels’ (a blend) are purchased.

Achillea millefolium - Yarrow
Landscape Use:
Best not to mix it in small beds - mass plant in large areas
“They{artemisia genus} include tarragon, one of the finest and most important ingredients in French cuisine, sweet annie, the source of a medicine crucially important for the prevention and treatment of malaria, and wormwood, the defining ingredient of vermouth, without which the martini could not exist
...According to the Greek myths, Artemis, the goddess of the wilderness and of the hunt, gave the power of the plant to Chiron the Centaur who was a great healer and teacher. It was Chiron who then developed the first medicines from artemisia… the bitterness impressed the early herbalists - Bitter herbs kick-start the digestive system, stimulate the liver, and boost the immune system
absinthe is flavoured with Roman wormwood (Artemisia pontica) and common wormwood (Artemisia absinthium), and those same wormwoods are used to make vermouth, the essential ingredient of the martini. Indeed ‘absinthe’ is the French word for wormwood and ‘wermut’ (pronounced ‘vermut’) is the German word, which goes to show how deep is the connection between the artemisias and some of Europe’s classic alcoholic drinks. The liqueur chartreuse is made with black wormwood (Artemisia genipi) and other herbs. Another classic European liqueur, genepi, is made with the same black wormwood… Herbal bitters were developed for medicinal purposes, going back hundreds or thousands of years. They are made with dozens of herbs but the common thread through most of them is artemisia. It is interesting how bitters are typically taken in Europe: after a heavy dinner the evening would end with a shot of bitters. Bitters help the body to digest the meal, by firing up the digestive system. They help the body process food quickly and help to settle the stomach before retiring for the night.
Artemisias are important to native Americans for traditional ceremonial use. Dried leaves tied into small bundles called ‘smudge sticks’ are burned to purify the ritual area. Like incense, a burning smudge stick releases fragrant essential oils into the air. These volatilized oils often have antibacterial and antifungal properties, which may hint of why smudging is associated with purification (we have one native here)
Early hunters faced a constant battle with worms and other intestinal parasites from the meat they ate, something we no longer worry about because our meat is government inspected to ensure it is sanitary. Taking wormwood would have cleared those intestinal infestations because wormwood is a powerful vermifuge, or an agent that expels worms. Free of parasites they would have felt stronger and healthier.
This plant is not grown for its flower and it is, in fact, rarely seen or noticed.
Typically this plant will be sheared back to about 7.5 cm above ground and made to regenerate for a second flush of foliage rather than allowing it to bloom.
