Plants have been used medicinally by humans for millennia. Tulsi is one of these drugs. A plant's perfume emanates from within. It is found all over India. It is harvested around Hindu temples or places of worship. Its leaves, seeds, and roots are employed in Ayurvedic treatment. Tulsi contains a variety of nutrients and bioactive compounds. Tulsi's key chemical components are Linalool, caryophyllyne, Oleanolic acid, and Rosmalinic acid. Tulsi standardisation has been used in modern science. Two active ingredients are eugenol (essential oil) and ursolic acid (acide). A diaphoretic, anti-periodic, and anti-bronchitis leaf. A decoction of the leaves can treat coughs, malaise, and colds. Not only is it moisturising. Flowers' oils can treat ringworm. Because of its antibacterial and antifungal characteristics, Ocimum sanctum has been used in numerous therapeutic trials. This page discusses the chemistry and pharmacology of Ocimum species.

COVID-19 outcomes may be more severe in lung cancer patients. As a COVID-19 pandemic spreads, it's critical to identify which people and malignancies are most susceptible. COVID-19 appears to have the worst results in lung cancer patients. Lung damage or reduced lung capacity can be caused by the disease itself or by cancer treatments such as radiation and surgery. The earlier lung cancer is diagnosed, the better the prognosis. As a result, early detection technology for cancer is in high demand. Early diagnosis in large population screens is closely connected to non-invasiveness and cost-effectiveness. As a result, microelectronic-based sensor technology may be used to construct sensitive biomarker detection systems. Various biosensors have recently recognized cancer-related proteins. Researchers are increasingly interested in testing for volatile metabolites found in the breath. Companion testing for innovative anti-cancer drugs and re-biopsy for new therapeutic uses are helping to speed up the development of lung cancer diagnostic tests. This review covers all current lung cancer diagnostic modalities in depth.

The  Kigelia pinnata (Lam) Benth is a species of the Bignoniaceae family commonly known as Kigelia africana is locally known as waghul phul.  The adult sausage tree has spectabular fruits these can weigh several kilogram hence the tree English common name worsboom.  Wherever the trees grows it is usually evergreen especially places where rainfall occurs throughout the year but deciduous in places of long dry season. Kigelia pinnata is renowned for its traditional application as anti-inflammatory, anti-diabetic, anti-oxidant, anti –microbial, and anti-cancer effects.  It contains chemical constituent like kigenol, kigelinone7, kigenol12, iso-kigenolls. In the present work pharmacognostic studies are carried out to investigate its medicinal properties.  The study consists of macroscopic character of the plant Kigelia pinnata physico-chemical parameters like total ash, acid insoluble ash, thin layer chromatography etc.  Keywords-  Kigelia pinnata,  pharmacognostic studies,  total ash, acid insoluble ash, thin layer chromatography
