Herbal Extracts in the Modern World: Trends, Applications, and Market Insights

Herbal extracts have been used for millennia. Plants with medicinal properties have been used to treat a wide range of human ailments for 5000 years, according to Ayurveda. 

As herbal extracts have several qualities like antimicrobial, antiseptic, anti-inflammatory, and antioxidant, they are mostly added to cosmetic formulations. Both urban and rural residents still rely on medicinal plants and herbs for traditional cosmetics.

Generally, extracts are categorized according to their form and/or the solvent that was used to create them. A few often utilized solvents are vinegar, glycerin, alcohol, and water. 

Different phytochemicals in a herb will be drawn to these solvents according to their inherent properties. Extracts obtained through decoction or infusion are used as the foundation for syrups and other products, as well as teas and rinses.

Herbal extracts are always available for buying in various forms. Extracted from the inert structural material of the plant that produced them, extracts are naturally occurring phytochemicals. 

The primary benefit of utilizing extracts rather than raw medicinal plants and herbs is that the phytochemicals are much more easily absorbed after being removed from the plant matrix.  

Herbal Extracts and Their Extraction Process

The first stage in separating the desired natural herbal extract from the raw materials is extraction. By the extraction principle, extraction techniques include solvent extraction, distillation, pressing, and sublimation. Although, solvent extraction is the most popular technique there are some other herbal extraction processes as well:

1. Maceration

Maceration is a very simple extraction method and could be used to extract thermolabile components.

• The solvents used are water, Aqueous, and Non-Aqueous Solvents.
• Temperature: Room Temperature
• Pressure: Atmospheric
• Time: Long Hours
• Volume of organic solvent consumed: Large
• The polarity of natural products extracted: Dependent on extracting solvent

2. Percolation

Since percolation is a continuous process where a new solvent is continuously added to the saturated solvent, it is more efficient than maceration.

• The solvents used are water, aqueous and non-aqueous solvents.
• Temperature: Room temperature, occasionally under heat
• Pressure: Atmospheric
• Time: Long
• The volume of organic solvent consumed: Large
• The polarity of natural products extracted: Dependent on extracting solvent

3. Hydro distillation and Steam Distillation

Commonly used methods for the extraction of volatile oils. Although some natural compounds may encounter decomposition.

• The solvents used Water
• Temperature: Under heat
• Pressure: Atmospheric
• Time: Long
• The volume of organic solvent consumed: None
• The polarity of natural products extracted: Essential oil (usually non-polar)

4. Reflux Extraction

Reflux extraction uses less solvent and takes less time than percolation or maceration. It is also more efficient. The extraction of naturally occurring thermolabile products is not possible with it.

• The solvents used Aqueous and non-aqueous solvents
• Temperature: Under heat
• Pressure: Atmospheric
• Time: Moderate
• The volume of organic solvent consumed: Moderate
• The polarity of natural products extracted: Dependent on extracting solvent

5. Soxhlet Extraction

Compared to maceration or percolation, the Soxhlet extraction is a high-efficiency, automated continuous extraction technique that uses less solvent and takes less time. Thermal degradation will be more likely due to the Soxhlet extraction's high temperature and extended extraction period.

• The solvents used Organic solvents
• Temperature: Under heat
• Pressure: Atmospheric
• Time: Long
• The volume of organic solvent consumed: Moderate
• The polarity of natural products extracted: Dependent on extracting solvent

6. Pressurized Liquid Extraction

This method uses a lot of pressure when extracting. The high pressure causes solvents to remain liquid above their boiling point, which increases the solubility and diffusion rate of lipid solutes in the solvent as well as the solvent's penetration into the matrix. 

• The solvents used Water, aqueous and non-aqueous solvents
• Temperature: Under heat
• Pressure: High
• Time: Short
• The volume of organic solvent consumed: Small
• The polarity of natural products extracted: Dependent on extracting solvent

7. Supercritical Fluid Extraction

Supercritical fluid (SF) is the extraction solvent used in supercritical fluid extraction (SFE). SF can dissolve a wide range of natural products and has similar diffusivity to gas and solubility to liquid. 

• The solvents used Supercritical fluid (usually S-CO2), sometimes with a modifier
• Temperature: Near room temperature
• Pressure: High
• Time: Short
• The volume of organic solvent consumed: None or small
• The polarity of natural products extracted: Nonpolar to moderate polar compounds

What are the types of Herbal Extracts?

Applications of Herbal Extracts

1. Herbal Medicines

Many populations have utilized herbal extracts as herbal medicines throughout human evolution, ever since people learned how to choose plants with medicinal properties for food and to treat and prevent illnesses.

Herbal medicines have been widely used since ancient times, and people have recognized their benefits due to their superior therapeutic qualities, lower toxicity, and side effects when compared to modern or synthetic medications, which have been clinically proven by certain studies. 

The active ingredients in medicinal plants and herbs are very soluble in water, but their large molecular size and difficulty in passing through lipid membranes limit absorption, which lowers their bioavailability and effectiveness. 

2. Food Industry

Food safety and quality can decline as a result of microbiological contamination or the intrinsic qualities of the food. 

Various strategies have been used to solve these issues. One such strategy is the use of preservatives. 

The demand for natural herbal extract and food preservatives has increased as a result of consumers' awareness and safety and toxicological concerns regarding synthetic preservatives. 

Considering their abundance and abundance of bioactive compounds, which serve as natural preservatives in a variety of food products, herbal leaf extracts are a better option.

3. Cosmetics

The market research shows an upward trend in the herbal trade with the herbal cosmetic industry playing a major role in fuelling this worldwide demand for herbals. 

The recent interest of consumers in herbal cosmetics has been stimulated by the decline of faith in modern cosmetics, the belief that plant remedies were natural and thereby superior to man-made synthetic cosmetics, and the reference to successful historical use by different cultures. 

These reasons have contributed to the increased acceptance as well as the manufacture of herbal cosmetics.

Market Size

The herbal extract market refers to the industry that extracts, processes, and commercializes bioactive compounds derived from plants for a variety of applications. Herbal extracts are used in a variety of industries, including pharmaceuticals, cosmetics, food and beverage, dietary supplements, and aromatherapy. 

They are used for their potential health benefits, flavoring, fragrance, and therapeutic purposes. The herbal extract market includes manufacturers, suppliers, distributors, and end users who produce and use these extracts.

FAQs

How are Herbal Extracts different from Whole Herbs?

Herbal extracts refer to chemical isolates from whole plants with medicinal properties to obtain a more concentrated dosage of active compounds with therapeutic efficiency. Herbal extracts are easily incorporated into consumer products. This is made possible by the typical lower volume of active compound extracts needed to affect a conventional end-user dosage.

How are herbal extracts integrated into daily consumer products?

Herbal extracts are widely used in daily consumer products such as dietary supplements, foods, beverages, and cosmetics for their health benefits and natural properties. 

What are the top trending herbal extracts in the market today?

The top trending extracts are Turmeric, Ashwagandha, Green Tea, Senna Leaf, Yohimbe, and Gymnema.

What should I consider when purchasing herbal extracts?

Consider the quality of the source herb, the extraction method in terms of potency and purity, certifications, and any fillers used.
