Stone Flower (Parmalia perlata): Introduction, Classification, Habitat, Botanical Description, Phytochemical Aspects, and Traditional Uses

Chharila, also known as Permalia perlata, is a plant in the Parmeliaceae family. The reason for some of its other common names, including Stone Flower, Patthar Phool, Shilaapushpa, and others, is likely due to its historical medicinal effect on ashmari (urinary stones) in the Ayurveda system of Indian medicine. Similar to Saxifraga ligulata, Didymocarpus pedicellata is also known as Patharphori (stone crusher), and both are used to treat kidney stones. A major component of parmelia species, usnic acid, demonstrated strong antimitotic, antitumor, and antimycobacterial effects. Other distinctive constituents, such as diffractic acid, gyrophoric acid, caperatic acid, etc., were also isolated and are well known for their analgesic, antipyretic, antispasmodic potential, and beneficial effects against hyperproliferative skin diseases like psoriasis, etc. There are three different types of parmelia, including P. perlata (L.) Ach., P. perofrata (Wulf.) Ach., and P. perforatum (Ach.) Mass., as well as P. sanacti-angelii Lynge, are offered as chharila in the Indian market. Tridecyl myristate, 3-ketooleanane, icosan-1-ol, usnic acid, parmelanostene permelabdone, atranorin, lecanoric acid, orcin, erythrolein, azolitmin, and spaniolitmin are only a few of the chemical components it includes. To improve the flavour and taste of food, P. perlata is typically used as a spice. Additionally, to have aphrodisiac potential, it possesses astringent, resolvent, laxative, and carminative qualities. Additionally, it helps with piles, scabies, leprosy, bronchitis, excessive salivation, toothaches, boils, inflammations, seminal weakness, dyspepsia, calculi, blood disorders, heart ailments, stomach problems, and general pain. In addition to a good cephalic snuff, drug smoke is thought to cure headaches, and powder is applied to wounds.

Body structure in Fungi
The bоdy struсture саn be uniсellulаr аs well аs multiсellulаr. In multiсellulаr, there is the fоrmаtiоn оf brаnсhed filаmentоus struсture. This is knоwn аs Hyрhаe. the hyрhаe аre the bаsiс unit оf fungus. These hyрhаe will аggregаte fоrming а tissue-like struсture. This tissue-like struсture thаt is fоrmed is саlled myсelium. But it is nоt а true tissue thаt is why it is knоwn аs lооse tissue.

Lichens: Economic Importance

Lichen: Definition
Lichens are a small group of curious plants. Lichen represents the permanent association between Algae and Fungi. This association is a symbiotic association, it means both the partners are mutually benefitted. The Algal partner which is associated with the body of the lichen is called Phycobiont and the fungal partner is called Mycobiont.
The Algal partner forms only 1-5% of lichen body (lichen thallus). In the phycobiont, the members which are present belong to Chlorophyceae and BGA. The phycobiont forms food for the fungi and performs photosynthesis. If the phycobiont is GBA, then it is involved in nitrogen fixation such type of lichen which can perform Nitrogen fixation is known as Azotodesmic.
In the mycobiont, the fungal partner belongs to Ascomycetes but in a few cases, it can also be a member of Basidiomycetes. Mycobiont protects algae. It will form a protective covering along phycobiont (Algal partner). Along with that it also helps in the attachment of lichen to a different surface. It also assists with water and mineral absorption.
