Euphorbia hirta L .

Common Hindi name: Dudhi.

Plant: 15-50cm. Common annual herb.


Leaves: Vary from green to coppery-red, depending on its habitat.

Flower: 7x6mm across.

Native to India and most tropical countries. Seen along roadside from coast to plains, up to 1,400m on the hills.


Used in traditional medicine and eaten as vegetable. A famine food, used when all else fails.

As per some recent researchers: The sap contains a latex which is toxic on ingestion and highly irritant externally, causing photosensitive skin reactions and severe inflammation, especially on contact with eyes or open cuts. The toxicity can remain high even in dried plant material. Prolonged and regular contact with the sap is inadvisable because of its carcinogenic nature.

Asthma weed has traditionally been used in Asia to treat bronchitic asthma and laryngeal spasm, though in modern herbalism it is more used in the treatment of intestinal amoebic dysentery. It should not be used without expert guidance, however, since large doses cause gastro-intestinal irritation, nausea and vomiting.


The plant is anodyne, antipruritic, carminative, depurative, diuretic, febrifuge, galactogogue, purgative and vermifuge. The aerial parts of the plant are harvested when in flower during the summer and can be dried for later use.


The stem, taken internally, is famed as a treatment for asthma, bronchitis and various other lung complaints. The herb relaxes the bronchioles but apparently depresses the heart and general respiration. It is usually used in combination with other anti-asthma herbs such as Grindelia camporum and Lobelia inflata. It is also used to treat intestinal amoebic dysentery.


The whole plant is decocted and used in the treatment of athlete's foot, dysentery, enteritis and skin conditions. It has been used in the treatment of syphilis.


The sap is applied to warts in order to destroy them. The treatment needs to be repeated 2-3 times a day over a period of several weeks to be fully effective.

How to Plant Flowers

    Planting annual and perennial flowers is an easy task, but with a few tips, your flowers will get off to a fast, healthy start that will reward you with bigger and better blooms down the road.

        It's best to plant when it's not especially hot or sunny. An overcast day when rain is forecast is ideal − your watering will get done for you.


       Plant most annuals and perennials after or before your season's last frost date. While spring is the most popular time to plant, perennials often do fine if planted in early fall in the North; late fall in the South. Northern gardeners also have the luxury of planting throughout much of the summer as long as the day isn't especially hot − say, over 75 degrees.
