A species of Euphorbia called Euphorbia peplus, also known as milkweed, small spurge, radium weed, cancer weed, and other names, is endemic to most of Europe, northern Africa, and western Asia. It typically grows in gardens, disturbed terrain, and cultivated arable land. [1][3][4]
It has become very widely naturalized and frequently invasive outside of its original habitat, and this includes Australia, New Zealand, North America, and other nations in temperate and subtropical regions.

Spurge: Is it a weed?
This weed spreads into crevices in vegetable gardens, landscaping beds, and sidewalks.
Spotted spurge (Euphorbia maculata), a spotted plant that grows best in the summer heat, invades flower beds, gaps in the pavement, and vegetable gardens in addition to weak spots in the lawn. Spotted spurge is easily identified by its tiny, dark-green leaves with a red spot, hairy red stems that branch out from a central point, and dense, mat-like form. This annual weed sprouts in the middle of spring and blooms all summer long inconspicuously with small green flowers. Spotted spurge can be differentiated from other weeds in addition to having distinctive red spots by the milky sap that is released whenever any portion of the plant is injured. It can create a thick mat that is up to three feet across in the thinnest parts of the lawn.
How to Kill Spotted Spurge
Spotted spurge may swiftly spread over weak spots in your lawn and generate thousands of seeds per plant. While seeds planted later in the year will remain dormant in the soil until the following spring, seeds planted in the early summer will grow practically immediately. Only 5 weeks after germination, this warm-weather weed begins to blossom and produce seed, making early discovery and treatment essential.
Delete a few spots. Spotted spurge is a suitable option for hand-pulling if there are only a handful spread across the yard because of its flat shape and single taproot. When removing this sort of plant by hand, be sure to grab everything—including the roots—because it tends to break off at the stem. Otherwise, it will sprout again. When hand-pulling spotted spurge, always wear gloves because the plant generates a sap that can be irritant to the skin. Remove spotted spurge before it can flower and generate seeds to help reduce the likelihood of it returning.
Another option is to use a ready-to-use lawn weed killer, such as Scotts Spot Weed Control for Lawns, to eradicate small spots of spotted spurge plants. Follow the label’s instructions carefully, and only apply to the grass types mentioned.
Kill substantial patches. Apply a solution designed for broadcast application to your grass if you have a significant spotted spurge infestation. Use a product like Scotts Turf Builder Triple Action or Scotts Turf Builder Weed & Feed3 to control weeds and feed your lawn at the same time. Try Scotts Turf Builder Southern Triple Action or Scotts Turf Builder Bonus S Southern Weed & Feed2 if your lawn is St. Augustine, centipede, or zoysia.
How to Prevent Spotted Spurge
Feed your grass. Regular feedings (2 to 4 times year) give your lawn the nutrients it needs to grow thick, luscious turf. Since spotted spurge is not a competitive weed, it will be kept out and weed seeds won’t be able to germinate in a thick lawn.
Graze high. The grass can grow thick and form a deep root system when it is mowed at the height that is optimal for the sort of lawn that you have. Lawns made of Kentucky bluegrass, perennial ryegrass, fescue, and St. Augustine benefit from a 3 to 4 inch mowing height. While Bermuda lawns enjoy a 1.5 to 2 inch height, zoysia and centipede lawns perform best when mowed at 2 to 3 inches. Leave grass clippings on the lawn rather than bagging them to aid in the soil’s nutrient recycling.
Deep breathing. By promoting deeper root growth and thicker, tougher grass, infrequent, deep watering helps your lawn outcompete weeds. Too little or too often watering promotes shallow root growth, which can result in a thin grass and bare patches that weeds will exploit. To get the 1 inch of water per week that most lawns require, rely on rain (nature’s sprinklers) as much as you can, and only use sprinklers when absolutely necessary.
Are weeds Euphorbia maculata?
The annual plant Euphorbia maculata, often known as spotted spurge or prostrate spurge (not to be confused with Euphorbia prostrata), is a member of the Euphorbiaceae family and is a native of North America. In the US, it is a typical weed of lawns and gardens.
It serves as a pioneer plant in ecological succession and may grow in a variety of soil types and sunny areas. This plant’s sap is a moderate skin irritant that in some persons might result in a rash. The sap is toxic and is said to cause cancer. [2] [3]
Is spurge considered a weed there?
In southern Australia, sea spurge (Euphorbia paralias) is a prominent environmental weed. Sea spurge infestations in Victoria and Tasmania are probably the source of the ocean-dispersed seed that is steadily encroaching on NSW coastal dune habitats.
The foliar blight fungal pathogen Venturia paralias (formerly known as Passalora euphorbiae), which causes severe sea spurge disease in its native area in Europe, is the subject of this sub-project. In-depth host-specificity testing was carried out in an Australian quarantine facility to evaluate any dangers the fungus might present to plant species that are not the target species. As a result of the findings, which showed that the fungus does not threaten non-target species, permission for its distribution in Australia was requested from the appropriate authorities. Since the biocontrol agent’s release was authorized in November 2020, research has been done to create efficient production and field release procedures. Beginning in the spring of 2021, a release program for the agent that targets marine spurge infestations in south-east Australia was started.
Describe radium plant.
cycle of life Annual Size: 20 cm Position: Partially in the sun Preference for well-drained soil
One Radium Weed Herb Plant in a 50 x 75mm tube and general growing instructions are included.
Every one of our herb plants is grown using certified organic fertilizers and potting soil.
Other names for radium weed include petty spurge, milkweed, and cancer weed. It is a little annual garden weed that is widespread across Australia. It has branched branches with alternate oval leaves, inconspicuous yellow blooms, and a milky caustic fluid that flows from broken stems. The sap from this plant is utilized to remove sun spots, making it the most valuable component.
In the past, it has been used to cure warts, corns, and skin malignancies, and it is true that a sap constituent can make these skin lesions go away.
As a straightforward topical treatment for some skin malignancies, such as basal cell carcinomas and squamous cell carcinomas, a business in Australia by the name of Peplin Biotech is conducting research and creating a gel from the sap of Euphorbia peplus.
For 2-4 days, the milky sap can be applied on sunspots. Just a drop of the sap is all that is necessary to treat the region. The wound will become fairly unattractive and fester before developing a scab and fresh pink skin. To speed up the healing process, apply fresh aloe gel.
Avoid making touch with internal organs and the eyes. The sap will corrode soft tissues and burn them.
Growing Conditions
Self seeds readily throughout the garden, will grow in poor soils and difficult positions, but grows better in a well watered position in sun to semi sun.
In cooler southern areas, it will grow throughout the summer. In South East Queensland, it grows best during the cooler months.

How can a weed be recognized?
Identifying Weed Characteristics
- Leaf venation, margins, and form (branching pattern of leaf veins)
- leaf arrangement (simple or compound)
- The position of the leaves on the stem.
- the existence or lack of hairs on the plant’s leaves or other components.
- flower shape, color, and size
Are spurge weeds edible?
Another reddish-colored, sprawling plant is the spurge (Euphorbia spp.). In the continental US, Hawaii, and southern Canada from Quebec west to British Columbia, there are numerous different species of spurges. They should not be consumed since they are poisonous. The most reliable way to distinguish spurges from purslane is that when broken, the spurge’s leaves and stems leak a white latex. Additionally, whereas purslane leaves are succulent, spurges’ leaves are not. While the leaves and stems of purslane are frequently hairless or have only a few little hairs, those of spurges are sometimes densely to sparsely hairy.
Purslane: Is it a weed?
In field crops and lawns, purslane (Portulaca oleracea L.) grows as a weed naturally. Purslane is a plant that is found all over the world and is widely used as a culinary herb in many parts of Europe, Asia, and the Mediterranean area. Mucilaginous compounds found in this plant have therapeutic use. It has the potential to be used as a vegetable source of omega-3 fatty acids and is a rich source of potassium (494 mg/100 g), magnesium (68 mg/100 g), and calcium (65 mg/100 g). Of all green leafy vegetables, it is a particularly good source of alpha-linolenic acid (ALA) and gamma-linolenic acid (LNA, 18: 3 w3) (4 mg/g fresh weight). It had the highest concentrations of alpha-tocopherol and ascorbic acid (22.2 mg and 130 mg per 100 g of fresh and dry weight, respectively) (26.6 mg and 506 mg per 100 g of fresh and dry weight, resp.). Purslane leaves were found to contain 671869 mg of oxalate per 100 g of fresh weight. Purslane is useful for human consumption due to its high antioxidant content and nutritional value. It demonstrated the herb’s enormous nutritional potential and suggested potential uses for it in the future.
Describe sedge weed.
Why Do Sedge Weeds Exist? Sedges are perennial plants that grow in damp soil or shallow water. The height of these weeds varies by species and can be up to 4 feet. They have a grass-like look and frequently form dense clusters.
A weed, is matted sandmat?
I first spotted these creeping, matting weeds in my garden growing between the stepping stones a while back. I chose to give them a chance because I found them to be intriguing. I’m glad I decided to let them grow rather than pull them up. Now that they have expanded and multiplied, they have filled in the gaps between the stepping stones. They hold the soil in place and cover the ground, preventing erosion without the need for watering or fertilizing—true sustainability. Occasionally, if they begin to extend beyond the stepping stones, I pull a few of them here and there.
How can I recognize these weeds, and what are they? Even while some Master Gardeners (MGs) may know everything, I do not. However, we have access to a wealth of data based on study.
One such resource is the Weed Research Information Center website at the University of California (http://weedid.wisc.edu/ca/weedid.php). It assists with weed identification in a step-by-step fashion.
The first question requests the type of weed: broad leaf, grass-like, or woody. The next step, which requests many plant features, is step 2. A good-sized sample of the marijuana should be in front of you at all times. I am able to positively identify my good marijuana about 30 minutes later. (Having reading glasses or magnifying glasses also helps to identify things more quickly; without them, I could have missed the presence of milky sap or other subtle qualities.)
My weed is a creeping spurge, also known as a matted sandmat, as I discovered (Euphorbia serpens or Chamaesyce serpens). It is a yearly that originated in South America. It grows in the form of a mat of prostrate stems that root at nodes where the stems touch the ground. The milky sap, like every other member of the Euphorbia family of plants (including poinsettia), is poisonous and, at the very least, irritant to the skin. It isn’t a problem for me because it is a groundcover.
Therefore, the next time you notice an unfamiliar plant, wait before removing it. Always remember to use integrated pest management, or IPM. Always make an effort to identify it before moving further.
Are humans poisoned by spurge?
The alkaloid euphorbon, which is harmful to both people and animals and is a recognized co-carcinogen, is present in leafy spurge. When in touch with the eyes, the plant’s white, latex secretion can significantly hurt both human and animal skin.
What is the purpose of tiny spurge?
Ingenol 3-angelate (or PEP005; 21), a peculiar diterpene ester derived from Euphorbia peplus L. (Euphorbiaceae), often known as petty spurge/radium weed/cancer weed, is now produced by Peplin Ltd. in Queensland, Australia. Studies on the topical usage for treating actinic keratoses and nonmelanoma skin cancer are the most advanced. Additionally, it was created for systemic leukemia therapy of intravesicular bladder cancer. E. peplus was frequently used to cure warts and other skin diseases in Europe and Morocco62. Numerous other temperate nations, including Australia, were also exposed to the species. Australians employed the sap from E. peplus to treat sun keratoses and skin malignancies during the 1970s and 1980s. 63 According to A. C. Green and G. L. Beardmore63, E. peplus is the second most often used plant product for treating these illnesses in Brisbane, Australia. Only Aloe Vera was employed more frequently (35 reports). In all, 164 people (out of 2095 respondents) admitted to treating their own solar keratoses and skin malignancies. Of these, 8 utilized E. peplus, whereas 75 used herbal remedies. 63 Carica papaya was another another widely used remedy (8 reports). Even though this is a small sample size, it is apparent that it was used as a beginning point to research the species’ medical effects64, demonstrating the clear ethnopharmacological motivations behind this R&D endeavor. The initial LD90 of Ingenol 3-angelate (PEP005) against a variety of human and mouse cell lines was 180220 mol l1. The most successful treatment, according to in vivo tests employing different tumors implanted into mice, was a topical application for three days of 42 nmol prepared as an isopropanol-based gel. The substance caused an abrupt erythema. Mechanistic studies showed that the plasma membrane was rapidly disrupted, the mitochondria swelled, and primary necrosis led to cell death. There is experimental support for the idea that neutrophil-mediated antibody-dependent cellular toxicity is crucial at a later stage. Apoptosis is induced in primary acute myeloid leukemia cells and myeloid leukemia cell lines at nanomolar concentrations by ingenol 3-angelate in vitro, which exhibits strong antileukemic effects in a wide variety of cell lines. 65 The correlation between this activity and the expression of PKC- was then determined (protein kinase ). It’s interesting to note that it caused PKC to translocate in a manner distinct from that of the well-known tumor copromoter PMA (phorbol 12-myristate-13-acetate, or PTA). Ingenol 3-angelate promotes a fast translocation of PKC- simultaneously to the internal membranes and the nuclear membranes at low doses (10 nmol ml1). Contrarily, PKC- is made to translocate first to the nuclear membrane and then to the plasma membrane by PMA. 64 The activity of targets in the nuclear factor kappaB (NF-B) pathway is also altered by ingenol 3-angelate. This task requires a lot of time and complexity. A biphasic activation of p65 and, to a lesser extent, C-Rel, was seen up to 6 hours following ingenol 3-angelate administration. 64 Phase III clinical trials for topical usage are anticipated to begin in 2008.
This case provides some astounding insights into the complexity of contemporary drug discovery, particularly when it comes to the research’s ethnopharmacological connections. This discovery was unquestionably influenced by local and traditional knowledge. It is based on so-called “indigenous” European knowledge that was undoubtedly passed down from one generation to the next and that was brought to Australia along with the Europeans who first used the plant. According to the academics and the business responsible for the discovery,66 the original concept was used in Brisbane, Australia. Hypothetically, if this were a species that the Europeans had brought back from India or what is now Spanish-speaking America, this finding would undoubtedly set off a heated debate over who should possess the traditional knowledge. The possibility to transition from one therapy area (in this case, topical treatments for various types of skin cancer and precancerous diseases) to other therapeutic purposes that are only loosely related to the initial use is highlighted by this discovery on a pharmacological-clinical level.
The proliferation of melanoma cell lines was first demonstrated to be selectively inhibited by betulinic acid, a pentacyclic triterpene present in many higher plants, notably Betula spp. (where it is the most prevalent secondary metabolite). Historically, a number of inflammatory skin disorders have been treated topically with extracts from the Betula species. As a blood purifier and diuretic, general tonic, and as an ointment for persistent scabs and rashes (Cree), gonorrhea (Cree. Iroquois), skin rashes (Algonquin, Cree), and infections, species of the genus have been used in North America specifically for a variety of gastrointestinal conditions (e.g., removing bile from the intestines, diarrhea (Micmac). 47 In Europe, members of the genus are also extensively used. In the past, it was used for dropsy, wounds, and gout. Nowadays, it is frequently used to encourage hair growth and as a diuretic/cleansing agent. 70 Several efforts on new anticancer drugs are currently concentrating on the betula species. Traditional usage (such as those as an anticancer agent) and contemporary biological research don’t appear to have any direct ethnobotanical connections. This is hardly surprising considering the limited number of species that have been used as anticancer drugs. Many of these applications, however, assume that the extract will affect the cell cycle, a characteristic that is being researched in the creation of brand-new anticancer drugs. Betula successfully causes apoptosis in neuroectodermal malignancies and has been demonstrated to be a powerful inducer of cell death in cell lines originating from human leukemia. 71,72 In a number of cell lines, this activity is connected to NF-B activation. As a result, NF-B inhibitor combination therapies would not be therapeutically beneficial, although the medicine may have potential if administered in the right combinations. Investigations are also being done into its potential as an antiviral agent. 74
The final illustration shows a South American treatment for cancer and tumors. A canopy tree native to the Amazonian rainforest called Red Lapacho tea gained notoriety for the first time in Brazil and Argentina in the 1960s. The plant-based medication is frequently used in local and traditional phytomedicine to treat a variety of ailments, including bacterial and fungal infections, fever, syphilis, malaria, trypanosomiasis, stomach and bladder disorders. It is typically taken orally as a decoction made from the inner bark of the tree.
Red Lapacho (Pau D’Arco) has been used in biomedicine since 1873, according to reports. Following press reports from Brazil, it gained international notice as a “miracle medicine” in 1967. The NCI conducted a thorough investigation of T. impetiginosa in the 1960s. Lapachol (23) and -lapachone, two major bioactive substances, have been identified from T. impetiginosa (24). – The primary anticancer chemical is lapachone, and proapoptotic effects have been seen in vitro. The molecular effects of this substance have been the subject of some mechanistic studies. The quality and composition of the botanical (drug) material that is now sold on worldwide markets appear to differ, making it difficult to evaluate the precise therapeutic claims made by the products. No pharmacological lead based on this species appears to be in development at the moment. The lack of bioscientific support for products made from T. impetiginosa emphasizes the promise of such fresh leads as well as the dangers of exaggerating a (botanical) drug’s therapeutic potential based on scant (usually in vitro) evidence. 75
