![]() ![]() Stalks usually form fleshy green whorls, becoming yellow during the summertime, and returning to red in the winter ( 2 ). These findings indicated that euphol is an active agent in Euphorbia tirucalli that exerts anticancer activity by arresting the cell cycle of cancer cells. Cultivar: Characteristics: Euphorbia tirucalli is a perennial shrub with several loosely branching, pencil-thick, vertical stems ( 1 ). Reduced expression levels of cyclin A and B1 were also observed, corresponding to the decreased distribution of cells in the S and G2/M phases, respectively. Furthermore, this effect was correlated with the downregulation of cyclin‑dependent kinase 2 (CDK2) expression and the upregulation of the CDK inhibitors p21 and p27. Further studies demonstrated that euphol treatment downregulated cyclin D1 expression and the hypophosphorylation of Rb. Treatment of the cells with euphol resulted in decreased cell viability, which was accompanied by an accumulation of cells in the G1 phase. Following the treatment of cells with different doses of euphol for 24, 48 and 72 h, the cell proliferation, cell cycle, and mRNA and protein levels of cell cycle regulatory molecules were analyzed, respectively. In the present study, we examined the anticancer effect of euphol, a tetracyclic triterpene alcohol isolated from the sap of Euphorbia tirucalli, in T47D human breast cancer cells. However, the mechanism of its anticancer effect is yet to be elucidated. If sap is exposed to eyes or swallowed, seek immediate medical attention.īest practice is always to keep houseplants out of reach of small children and pets.Euphorbia tirucalli is a long‑established treatment for a wide variety of cancers. ![]() Wear gloves when handling to prevent irritation from the sap wash hands well after handling. The sap of the Pencil Plant is quite toxic. Euphorbia tirucalli The Wonderful Sticks of Fire Plant. Common ProblemsĪs with all succulents, overwatering will lead to rot. Given the right indoor conditions, a Pencil Plant can grow to 6’. Average home temperature is generally suitable. Average home humidity is fine can tolerate dry air. Water every one to two weeks allowing soil to dry out between waterings. Euphorbia tirucalli, commonly known as the pencil cactus or milk bush plant, is used extensively for ornamental purposes in the southern United States and contains a toxic sap to humans. Thrives in bright indirect light to direct sun. In favorable conditions, it is able to grow between two and 20 inches in a single season. The Pencil Plant is otherwise very agreeable, surviving in nearly any condition that is both dry and above freezing. Height: 4-8 feet Width: 3-5 feet Exposure: Full Sun Irrigation (H2O Info): Low Water Needs Winter Hardiness: 30-32 F May be Poisonous (More Info): Yes Euphorbia tirucalli 'Sticks on Fire' (Red Pencil Tree) - This very striking succulent shrub is a form of Euphorbia tirucalli, a plant that eventually can grow to 25 feet tall by 8 to 10 feet wide. This succulent yields a highly toxic milky sap if broken or torn. Its leaves are small and slender and fall off quickly. Young branches are cylindrical, smooth, and green, but with age can turn gray and rough like tree bark. The plant’s namesake branches are pencil-like and grow upward in a candelabra pattern. The Pencil Plant or Euphorbia Tirucalli is a succulent native to South and East Africa. ![]()
