Schkuhria pinnata, the canchalagua or dwarf Mexican marigold, is a small, dainty, pioneer annual herb of the family Asteraceae and widespread in the tropics. It is regarded as a naturalised weed with low ecological impact.
Reaching 30–60 cm in height, this species is found as a pioneer on disturbed ground such as roadsides and ploughed lands. Leaves are mainly pinnatisect, with the upper leaves simple and filiform. The upper leaf surface is narrowly grooved, while both leaf surfaces are pitted with numerous small glands. Its capitula are numerous, terminal and small, with a solitary ray floret, its ligule 1.5–2 mm long and yellow, and 4-6 disc florets. Corollas are yellow to white sometimes with a purple tinge. Bracts are obovate, with a hyaline apex, while margins are minutely ciliate and glandular-punctate. Achenes are narrow-turbinate, 4-angled and some 4 mm long; there are 8 membranous pappus scales, darkly striated at apex.[ citation needed ]
The plant is native to South America, normally found in drier mountainous regions of 2000 – 3000 meters in elevation, and growing abundantly in the inter-Andean valleys. It is currently found in Latin America, Mexico, Africa, and in the southern United States. [1]
The Ketchwa indigenous people of the Andes have traditionally used this plant to treat a large number of conditions and ailments - they have used it as a bactericide in open wounds, to treat acne, malaria and inflammation, and as a blood purifier and diuretic. The plant can also be used as an abortifacients by inserting the root or infusing the whole plant and taking it orally. [2] [3]

Calendula officinalis, the pot marigold, common marigold, ruddles, Mary's gold or Scotch marigold, is a flowering plant in the daisy family, Asteraceae. It is probably native to southern Europe, but its long history of cultivation makes its precise origin unknown, and it is widely naturalised.
Kalanchoe pinnata, commonly known as cathedral bells, air plant, life plant, miracle leaf, Goethe plant, and love bush, is a succulent plant native to Madagascar. It is a popular houseplant and has become naturalized in tropical and subtropical areas.

Felicia amelloides, the blue daisy bush or blue felicia, is a hairy, soft, usually perennial, evergreen plant, in the family Asteraceae. It can be found along the southern coast of South Africa. It grows as ground cover and produces many very regular branches. It mostly grows to about 50 cm (1.6 ft) high, rarely to 1 m. The leaves are oppositely arranged along the stems, dark green in colour and elliptic in shape. The flower heads sit individually on up to 18 cm (7 in) long, green to dark reddish stalks. They consist of about twelve heavenly blue ray florets that surround many yellow disc florets, together measuring about 3 cm across. It is also cultivated as an ornamental, and was introduced in Europe in the middle of the 18th century.
Curculigo capitulata is a stout herb that belongs to the genus Curculigo. It is known by the common names palm grass, whale back, and weevil lily, and by various synonyms, including Molineria capitulata. It ranges from the Himalayas and eastern India through Indochina, southern China, Malesia, and New Guinea to Queensland and the Solomon Islands. The plant has yellow flowers and oblong, papery pleated leaves with very short stems. In China and India, the plant has traditional uses as medicine to treat diseases such as hemorrhoids, asthma, and consumptive cough. In Southeast Asia, the plant is also used as food wrapping and the fibres are used to make fishing nets, ropes and false hair. However, in recent years Molineria capitulata is more often used as ornamental plants in gardens. In recent studies, M. capitulata was also found to have potential in treating several chronic diseases due to its high antifungal, antioxidant, cytotoxic, thrombolytic, anti-inflammatory, and analgesic activities.
