[citation needed] Simarouba extracts are known to be effective only on specific types of human cancer cell lines and tests conducted were in vitro. Whether the same effect would be observed under in vivo conditions, depends on bioavailability and bioaccessibility; [citation needed] hence, Simarouba as an alternative cure for cancer remains ...
Extracts from Camptotheca (the "happy tree" or "cancer tree") were used to develop the chemotherapeutic drug Topotecan. Plant sources of anti-cancer agents are plants, the derivatives of which have been shown to be usable for the treatment or prevention of cancer in humans. [1] [2]
The leaves have broad oval to triangular stipules of about 7 mm (0.28 in) long and 4 mm (0.16 in) wide, a leaf stalk of ½–5½ cm (0.2–2.2 in) long, and a hairy or hairless, green to greyish green, sometimes with a differently colored semicircular band, more of less fleshy, circular to heart-shaped in outline, on average 3 cm (1.2 in) long ...

Leaf color varies from all-green to all-silver, but the most common is a Christmas tree or hastate pattern in silver or pewter and various shades of green.
Temperature Extremes. The ideal temperature range for a prayer plant is between 60 to 80 degrees Fahrenheit, says Langelo. Any temperature that is lower or higher can cause the leaves to curl.
It is an evergreen climber growing to 3–6 m (10–20 ft), with heart-shaped glossy leaves to 30 cm (12 in) long, and occasionally spathes of white flowers in mature plants. With a minimum temperature requirement of 15 °C (59 °F), in temperate regions it must be grown under glass or as a houseplant . [ 6 ]
The shape of the leaves varies among the species and even among different specimens of the same species. Cyclamen hederifolium and Cyclamen repandum usually have leaves shaped like ivy , with angles and lobes, Cyclamen coum has nearly round leaves and Cyclamen persicum has heart-shaped leaves with a pointed tip.
