An essential part of the Indian traditional medical system, Ayurveda, is the medicinal herb Pterocarpus santalinus, which has a variety of uses. The plant is well known for its unique wood, which is distinguished by its stunning hue and beauty. Triterpenoids, steroids, flavonoids, and phenolic acids may be present, according to phytochemical study. This drug is used to treat eye conditions, ulcers, induce vomiting, and cause mental disorders. Heartwood is well-known for its cooling, aphrodisiac, diaphoretic, anthelmintic, antihyperglycemic, antipyretic, anti-inflammatory, and tonic qualities. Promising skin protecting benefits can be seen in phytoconstituents such as pterostilbene, cedrol, savinin, lupeol, betulin, ?-eudesmol, and ?-bisabolol that have been extracted and employed in dermatological formulations. P. santalinus's pharmacological effects on health and disease are examined in this review, which also offers a current assessment of its phytochemical, pharmacological, and therapeutic applications.
Pterocarpus Santalinus, commonly known as red sandalwood, is a magical herb that has strong therapeutic and skin-care uses. It is an important component of traditional medicine because of its strong qualities and vivid red colour. The multilingual film Red sandalwood trees are popular, but their wood is trafficked into other nations, as Pushpa examines. Many years of fighting diseases taught man to look for pharmaceuticals in the bark, seeds, fruit bodies, and other parts of plants, which led to an awareness of the use of medicinal plants. Humans have been using medicinal herbs for a very long time—since ancient times. Original plant medicines, monuments, and written records all attest to their use. [1] Knowledge of their medicinal qualities has improved doctors' and pharmacists' capacity to address health issues. [2] Eighty percent of underdeveloped nations rely on traditional medicines for primary treatment, according to the World Health Organisation. In order to promote sustainable practices, rural populations gather medicinal herbs from forests.[3] It has frequently been documented that traditional medicines and medicinal plants are used as therapeutic agents to maintain good health in the majority of developing nations. [4] The tropical tree Rakthachandan, which belongs to the Fabaceae family, has several health advantages, especially its medicinally useful heartwood.
The deciduous P. santalinus tree has pink stripes and thick, dark brown bark. It creates santalin, a natural dye used in food colouring and pharmaceutical formulations.is the botanical name for Pterocarpus santalinus, a medicinal herb with anti-inflammatory, hepatoprotective, antipyretic, and anti-hyperglycemic qualities. Its leaves contain active phytoconstituents such as triterpenoid and steroids that exhibit antifungal action. In Ayurveda, its heartwood is used to treat ailments like skin, diabetes, headaches, and jaundice.[5]
In addition to standardising Ayurvedic and Siddha formulations that use Pterocarpus santalinus heartwood as a powder ingredient, microscopic analysis attempts to identify and authenticate the raw medication. Numerous phyto-constituents, such as acylated isoflavone glucoside, isoflavone-liquiritigenin, isopterocarpone, pterocarptriol, cryptomeridiol, and santalin A and B, are found in the heartwood of red sandalwood.
[9]Adulterants and substitutes: Adenanthera pavonina Wild heartwood. Also called 'Ranjana' and 'Raktakambal' on the West Bengali side. 'Bari Gumchi' is another name for it in Northern India. It is a member of the family Mimosaceae. Tree-derived sawdust and artificially coloured wood shavings are marketed as low-cost alternatives to red sanders and are used to treat wounds, inflammation, and illnesses. Heartwood and red dye from Adenanthera pavonina Linn, whereas red sandal wood is mixed with Rose wood, Padauk, and Bijasel because of their similar appearances [10]. Wood is used instead. [9]
HISTORY
The Fabaceae family's Pterocarpus genus of trees [6] is well-known for its precious timber, especially padauk, which is also known as mukwa or narra."Wing fruit" is the Latinized Ancient Greek scientific name, which alludes to the peculiar form of the seed pods of this genus. Originating from either African or Asian Pterocarpus species, padauk wood is prized for its strength, stability, and aesthetic appeal. There are currently 35 recognised and widespread Pterocarpus species in the world, according to research. [7, 8] These include Pterocarpus amazonum (Benth.), Pterocarpus angolensis, Pterocarpus acapulcensis, Pterocarpus albopubescens, Harms, Pterocarpus antunesii (Taub.), Pterocarpus echinatus Pers., Pterocarpus brenanii, Pterocarpus claessensii, and Pterocarpus dalbergioides Eraceus Pterocarpus, Gilletii Pterocarpus, The Pterocarpus hockii, homblei, and Pterocarpus indicus Pashu Padauk, Pterocarpus macrocarpus, Pterocarpus marsupium, Pterocarpus mildbraedii Harms, Mutondo Pterocarpus, Jacq. Pterocarpus officinalis Orbiculatus Pterocarpus DC, Pterocarpus rotundifolius (Sond.) Druce, Pterocarpus rohrii Vahl, Pterocarpus osun Craib, Santalinoides Pterocarpus, Santalinus Pterocarpus, Rizzini, Pterocarpus ternatus, Harms, Pterocarpus tessmannii Welw's Pterocarpus tinctorius .The majority of these species—Pterocarpus velutinus, Pterocarpus villosus Benth, Pterocarpus violaceus Vogel, Pterocarpus zehntneri Harms, and Pterocarpus zenkeri Harms—are found in Africa, particularly in Nigeria, Cameroon, Sierra Leone, and Equatorial Guinea, and some in Asia. The most significant and frequently used Pterocarpus species is Pterocarpus santalinus Linn. However, despite the species' growing demand, accurate data must be gathered.

GEOGRAPHICAL DISTRIBUTION
Pterocarpus Santalinus is an endemic species that grows in the hills of Andhra Pradesh, Karnataka, and Tamil Nadu. It has also been brought to Sri Lanka and is grown in Maharashtra, Odisha, and West Bengal. [14]
CULTIVATION AND COLLECTION
Traditionally, P. santalinus is propagated by vegetative and seed methods. Red loam soils that drain effectively and a hot, dry climate are necessary for seed germination. For early germination, seeds need to be treated with GA3 and benzyladenine. For growth, the plant needs 800-1000 mm of rainfall every year. It can be soaked in slurry made from cow dung or cold water. Topsoil is carefully mixed with 1015 kg of farm yard manure and 10 g of lindane dust to fill the 45 × 45 × 45 cm pits, which are dug at a distance of 4 × 4 m. To safeguard planting stock, pits are filled with lindane dust, dung, and topsoil. In order to shield the planting stock from soil-borne fungus, soil is combined with lindane dust and farm yard manure in pits. The best months to raise seeds are March through May. Crops should be planted in late May or early June, when it's raining, and watered as soon as possible after transplanting, with intervals of up to 15 days. [15]

USES
Fever, pain, and parasite infections may be lessened by Pterocarpus santalinus's antipyretic, anti-inflammatory, analgesic, anthelmintic, cooling, blood-sugar-lowering, anti-cancer, and antibacterial qualities. A natural cure for animal bites from spiders, snakes, or scorpions is red sandalwood, which can be applied as an antiseptic ointment. While Dal Chandan, when rubbed with honey, water, ghee, and oil, can help with visual abnormalities, Red Sandalwood paste can help with headaches.
As a chemotherapeutic agent, red sandalwood may be able to stop the growth of malignant cells and encourage apoptosis, which is the death of those cells. [29] Rakthachandan is a medicinal herb used in Ayurveda to treat ailments like diabetes, headaches, jaundice, skin disorders, inflammation, and wound healing. It has anti-inflammatory, hepatoprotective, antipyretic, and anti-hyperglycemic qualities. [30]

ADVERSE EFFECT
Red sandalwood might be safe if used sparingly. According to a 1996 case study by Sandra et al., red sandalwood powder can result in minor facial oedema, irritating erythema, and allergic contact dermatitis. It's critical to speak with your doctor right away and get the right care if you have any negative effects from using red sandalwood. Pregnant or nursing women should not apply the extracts to their skin, and they should be avoided if they cause irritation. [29]

NOVEL APPROACH OF P. Santalinus:
With sizes ranging from 1 to 100 nm, nanoparticles are crucial in many different technological domains. The new formulation provides tailored drug distribution above traditional dose forms. If the preparation is constructed of biodegradable components, it can provide long-term, continuous medication release. Thus, nanotechnology incorporates green chemistry. All components of the medicinal plant Pterocarpus santalinus, including the stem, bark, leaves, and seeds, have therapeutic benefits. Accordingly, the study shows that at high concentrations, red sandal-mediated silver nanoparticles have moderate cytotoxic and antioxidant effect. [40–45]
HOME REMEDIES
