Calotropis procera and C. gigantea, two soft-wooded, xerophytic shrubs of the family Apocynaceae, are used both historically and currently. Their uses are examined in light of the chemical makeup and biological characteristics of the plants. The use of plants as building materials, organic insecticides, animal feed, and for bioremediation are the main topics of discussion. Milkweed known as "Madar" or Calotropis gigantea (Crown Flower) is a plant that grows in Bangladesh, Sri Lanka, and India. The plant is a member of the Apocynaceae family, which also includes plants that produce latex. It is a significant medicinal herb that is used frequently in Ayurveda to control a variety of health risks. The objective of the current study is to identify the phytoconstituents that are present in the plant. The plant was found to mostly include phenolics, terpenoids, and flavonoids. The plant exhibited antibacterial properties as well. The plant's flavonoids were also tested for their potential to provide photoprotection. By utilising a UV visible spectrophotometer, it was discovered that the methanolic extract of leaves effectively absorbs ultraviolet light at wavelengths between 200 and 400 nm. The development of anti-UV dermatological applications may benefit from this.
