Definition

Neem is an all-powerful tree and a sacred gift from nature. The neem tree is primarily grown in the Indian subcontinent. Neem is a member of the Meliaceae family, which includes mahogany. Azadirachta indica (A. indica) A. Juss. is the botanical name for it today. Before the availability of written records that recorded the beginning of history, humans used neem extensively to treat a variety of ailments. Humans have been using neem since prehistoric times.

Azadirachta indica, the latinized name of neem, is derived from Persian. Azad means “free,” dirakht means “tree,” and i-Hind means “of Indian ancestry.” As a result, it literally means “the free tree of India.”

The neem tree is an incredible plant that has been designated by the United Nations as the “Tree of the Twenty-First Century.” In 1992, the US National Academy of Science issued a report titled “Neem: A Tree for Solving Global Problems.”

Neem in siddha

All parts of the neem tree are commonly used in traditional Indian medicine as a home remedy for a variety of human diseases. Siddha medicine is defined as the conquest of death: “that which ensures prevention against mortality.” This statement is attributed to Tirumular, a revered Siddha who wrote the Tirumantiram treatise. 

This medical system originated in Tamil Nadu, India. In ancient India, the system was widely used. The Siddha system of medicine is thought to be over 10,000 years old, making it one of the most ancient traditional medical systems. The Siddha medical system is prevalent in India’s southern states, Sri Lanka, Malaysia, and Singapore. Neem is the first medicinal plant mentioned in the Siddha medical system.

The uniqueness of the Siddha system is evident in its continuous service to humanity for more than 5 000 years in combating diseases and maintaining physical, mental, and moral health, while many of its contemporaries had long since become extinct.

Siddhars were spiritual adepts who possessed the eight supernatural powers known as the Ashta Siddhis. Siddha is derived from the word siddhi, which means the perfection of heavenly bliss. Sage Agathiyar is regarded as the guru of all Sidhars, and Lord Muruga is said to have given him the Siddha system.

Classification of neem tree

The neem tree is a tropical evergreen hardwood that grows in the tropics. It is related to the acacia tree and belongs to the mahogany family. The neem tree is native to the Indian subcontinent, but it can now be found all over the world. It is a fast-growing tree that can grow to be 60 to 80 feet tall. The neem tree has a drooping crown and a spreading crown. The compound leaves have 11 to 31 leaflets. 

The flowers are small and yellow, and the fruit is a drupe that is green when immature and brown when fully mature. The neem tree is a popular home garden tree that is grown for its shade, ornamental value, and oil production.

Uses of Neem

Almost every part of the neem tree is useful, and many of its medicinal and cosmetic applications rely on its antibacterial and antifungal properties. 

• Neem is commonly used in shampoos to treat dandruff, as well as soaps and creams to treat skin conditions such as acne, psoriasis, and athlete’s foot. It is also found in some toothpastes and mouthwashes, particularly in the Indian subcontinent, and young twigs are used as crude toothbrushes in rural areas. 

• Neem leaves have long been used as a traditional diabetes treatment, and there is some clinical evidence that it may help control blood sugar levels. 

• The neem oil extracted from the seeds can be used directly as an insect and mite repellent, insecticide, and fungicide, and it is the source of many commercial pesticide products such as dusts, granules, and concentrates. Pregnant women should avoid consuming neem oil, neem bark, and neem leaves because they can cause miscarriage.

• Azadirachtin, the main active insecticidal ingredient, works to disrupt the hormones involved in insect moulting, preventing larvae from developing properly into adults and acting as a feeding inhibitor. On contact, neem oil kills soft-bodied insects and inhibits mating and reproductive behaviour, reducing pest fecundity. Neem oil is used as a fungicide to control rust, black spot, mildew, scab, anthracnose, and blight. Because neem oil degrades quickly when exposed to ultraviolet light, repeated applications are frequently required. 

• Neem-based pesticides are commonly used in organic farming because they are low in toxicity to mammals.
