Guggul (Commiphora wightii)

Guggul (Commiphora wightii) is an important plant due to its renowned medicinal properties

The plant's resin, known as gum guggul, is rich in bioactive compounds like guggulsterones, which are recognized for their antiinflammatory, hypolipidemic, and antioxidant effects.

Research has shown that guggul possesses cholesterol-reducing properties due to compounds like guggulsterone. This bioactive compound aids in cholesterol metabolism by regulating bile acid synthesis and transport

The resin's chemical composition includes minerals, gum, terpenes, sterols, essential oils, and other bioactive compounds

Leguminous crops: Chickpea, Groundnut, Soya bean and lentils such as pigeon pea (tur)

 

Leguminous crops, including chickpea (chana), groundnut, soya bean and lentils such as pigeon pea (tur), have a unique biological capacity to fix atmospheric nitrogen in the soil, reducing the need for nitrogen fertiliser and, in turn, N2O emissions. 

A meta-analysis published  in 2023 shows that legumes fix about 70 kg of nitrogen per ha, equivalent to 152 kg of urea. 

This natural fertilisation supports sustainable plant growth and soil fertility, while improving the availability of other macronutrients. 

The study says soils under legume crops show more than 11 per cent higher NPK (nitrogen, phophorous and potassium) availability and 16-17 per cent greater carbon seque stration than cereal monocultures. 

Legumes also require 25 per cent less irrigation water than non-legume crops. 

Sal or Shorea robusta

 

Shorea robusta is an evergreen tree with an elongated crown when young, becoming more rounded as the tree ages. It can grow up to 50 metres tall in fertile soils, but is more likely to be 20 - 25 metres tall in poorer soils. The straight, cylindrical bole can be unbranched for up to 25 metres and up to 200cm in diameter

Sal is a very important multi-purpose tree. It is one of the main commercial timbers of India, being harvested from the wild for local use and export. It also yields a resin that is traded and an oil that is used locally as well as being exported in large quantities. It addition, it supplies tannins, an edible seed and medicines for local use. The leaves are used commercially for making plates and containers

].
The sal tree is often the dominant species in the forests of the sub-Himalayan tract, but overutilization of it for fuel, timber, fodder etc is becoming a cause for conservation concern in some areas

The seeds are a source of 'sal butter', an oil that is used in cooking like ghee and as a substitute for cocoa butter in making chocolate

The resin is valued for its use in the treatment of dysentery, gonorrhoea, boils and toothaches

The leaf juice is used in the treatment of dysentery

 The leaves are warmed and used as a poultice on areas of the body that are swollen

 They have a quick effect[. They are also applied to the stomach of children with dysentery

The oil from the seed is used to treat skin diseases

When tapped, the tree exudes large quantities of a whitish, aromatic, transparent resin known as 'lal dhuna'. It is used to caulk boats and ships and as incense. In some places in the Upper Tista forests of the Darjeeling District, large
pieces, often 450 - 600 cubic centimetres in size, are found in the ground at the foot of the trees[

The leaves are widely used for making plates, cups and for wrapping

An oil obtained from the seed is used for illumination

The bark is a source of tannins

The heartwood is a dark, reddish brown; the thin band of sapwood whitish. The grain is strongly spiralled and rather coarsely structured. The wood is hard, heavy, very durable and highly resistant to termite attack. Seasoning can present problems. The wood is easy to saw, but because of its high resin content, it is difficult to plane and turn; it has a tendency to split when nails are driven into it. This important Indian hardwood is especially well suited for constructing structures subject to heavy stress in houses etc, it is also used in hydraulic engineering, ships and railway cars, poles, railway ties and posts, simple interior finishing such as window frames and floors, and many other applications[

. For making household or agricultural implements, the coppice shoots are used

The wood is an important local source of fue

Litchi fruit

 

  Litchi fruit is having excellent quality

  It is a rich source of Vitamin C along with B complex vitamin. About 100 g of fresh lychee (roughly a small handful) provides around 70 mg of vitamin C, supporting immune function and collagen formation

 Minerals and plant compounds: It contains potassium and polyphenols (antioxidants such as epicatechin).

The Geographical Indication (GI) status has strengthened the identity and market recognition of Tezpur Litchi, enhancing its appeal among international buyers and creating new opportunities for premium agricultural exports from Assam.

As a traditional Chinese medicine, litchi has been used for centuries to treat stomach ulcers, diabetes, cough, diarrhea, and dyspepsia, as well as to kill intestinal worms.

Both in vitro and in vivo studies have indicated that whole litchi fruits exhibit antioxidant, hypoglycemic, hepatoprotective, hypolipidemic, and antiobesity activities and show anticancer, antiatherosclerotic, hypotensive, neuroprotective, and immunomodulatory activities.

 The health benefits of litchi have been attributed to its wide range of nutritional components, among which polysaccharides and polyphenols have been proven to possess various beneficial properties. 

The diversity and composition of litchi polysaccharides and polyphenols have vital influences on their biological activities

Caution:

Unripe lychee contains the chemicals Hypoglycin A, which causes severe vomiting, and methylene cyclopropyl-glycine (MCPG) which causes a sharp drop in sugar levels in blood

Hypoglycin A is an amino acid that is naturally found in the unripened lychee, while methylene cyclopropyl-glycine MCPG is a poisonous compound present in the seeds of lychee.

Malabar Tamarind (Garcinia Cambogia )

 

Garcinia cambogia is an expensive spice used for dried sun rind, in particular for fish curries, often used for flavors.

The plant is widely used by tribal people as a meal or dietary supplement, as well as in the treatment of different diseases such as stomach issues, skin diseases, and weight reduction treatments. 

The peel of the fruit contains high amounts of hydroxycitric acid (HCA), which is the active ingredient believed to be responsible for most of its weight loss benefits.

Hydroxycitric Acid (HCA), appears to block an enzyme called citrate lyase, which your body uses to make fat.

Note:- The majority of research agrees that taking Garcinia cambogia in the recommended quantities, which is up to 2,800 mg of HCA per day, is safe for healthy persons

 What Garcinia cambogia fruit  contains ? 

 The rind contains:

1) protein (1%), 

2)tannins (1.7%), 

3)total sugar (4.1%), 

4)pectins (0.9%) and 

5)fat (1.4%), 

6)moisture (80.0 g/100 g), 

All of the above have  shown to have important therapeutic properties

It was reported that Garcinia leaves contained 75% moisture, 2.3% protein, 0.5% fat, 1.24% fire, 17.2% carbohydrate, 14% iron, 25% calcium and 10% ascorbic acid, and 10% oxalic acid. 

The seeds are very rich in triglycerides stearic, oleic and stearic. 

The plant also has lactone and citric hydroxycitric acid but in small amounts

Aromatherapy : Essential oils

 

Aromatherapy is one of the most familiar uses. 

When inhaled, aroma molecules stimulate the olfactory system, which is closely linked to the parts of the brain that control emotions and memory. This is why certain scents can quickly calm the mind or lift the mood. Lavender oil is widely used to reduce stress, improve sleep and ease anxiety.

Essential oils are also commonly used in skincare:-

Tea tree and lavender oils are popular in skincare for their antibacterial and soothing properties and are often used to manage acne, minor wounds and skin irritation. When applied carefully and in diluted form, these oils can complement conventional treatments

What is Essential Oil?

Ans: 

Essential oils — highly concentrated aromatic extracts from plants, are no longer niche luxury products found only in spas or perfumes.

 They are increasingly used in food preservation, natural cosmetics, herbal medicines, bio-pesticides and eco-friendly household cleaners. This renewed interest is driven by a global shift towards cleaner labels, sustainable production and traceable supply chains.

Which are Aromatic crops ?

Ans: 

Aromatic crops such as lemongrass, mint, citronella, eucalyptus and vetiver.

Essential oils are natural, aromatic substances produced by plants and stored in different parts such as leaves, flowers, bark, roots and seeds. They are called “essential” because they capture the plant’s distinctive fragrance along with many of its beneficial properties. 

Leaves are among the most common sources of essential oils. Oils extracted from leaves often help plants defend themselves against insects and diseases:-

i)Eucalyptus oil, obtained from eucalyptus leaves, is widely used to relieve cold and breathing discomfort. 

ii)Peppermint oil from mint leaves is known for its cooling effect and is commonly found in balms, teas and digestive remedies

Flowers produce oils mainly to attract pollinators such as bees and butterflies. As a result, flower oils are often light, sweet-smelling and soothing:-

i) Jasmine oil is prized for its rich aroma and calming effect, while chamomile oil is commonly used to ease skin irritation, inflammation and stress.

Bark and wood contain oils that protect plants from pests and infections:- i)Cinnamon oil, extracted from tree bark, has a warm, spicy scent and is widely used for its antimicrobial properties. 

ii)Sandalwood oil, obtained from the heartwood of sandalwood trees, has a long history of use in perfumes, religious practices and skin care.

Roots and underground parts store strong-smelling compounds that can be highly potent. 

i)Ginger oil, derived from ginger rhizomes, is commonly used to support digestion and reduce inflammation. 

ii)Vetiver oil, obtained from grass roots, has an earthy fragrance and is widely used in aromatherapy for relaxation and mental balance.

Seeds are a less common source of essential oils, but they can produce powerful aromas:- 

Anise oil, extracted from anise seeds, has a sweet, liquorice-like smell and is traditionally used to aid digestion.

Essential oils reflect how plants interact with their environment, such as defending themselves, attracting pollinators and surviving stress, while offering humans natural solutions for everyday use.

 Many essential oils are known for their antimicrobial, anti-inflammatory and immune-boosting properties.

For topical application, essential oils should always be diluted with a carrier oil such as coconut, jojoba or almond oil.

Precaution: -

Applying undiluted oils can cause skin irritation or allergic reactions. A simple patch test on a small area of skin can help check for sensitivity. Ingesting essential oils is generally not recommended unless done under the guidance of a qualified healthcare professional. Many oils can be toxic if swallowed improperly or cause serious health problems. Some oils that are safe for humans can be harmful to animals and exposure through inhalation or skin contact may lead to adverse effects. When used responsibly and in appropriate amounts, essential oils can be both safe and beneficial.
