If you follow a healthy lifestyle, then you must have heard about Camellia sinensis leaf extract. If not, then you must head to green tea, which is well known for its health benefits.
Well, camellia sinensis is nothing but an extract of common tea leaves that has become popular in recent times.
Research claims that Camellia sinensis leaf extract has several bioactive substances that are mainly used for weight loss and skin health.
Other than these usages, this black-green or oolong tea is a great source of antioxidants, caffeine, L-theanine, and amino acids.
These substances help to boost the immune system and reduce stress and anxiety, as we have discussed in this article.
How Does Camellia Sinensis Leaf Extract Help In Boosting Immunity, Stress, And Anxiety?
To understand the health benefits of camellia sinensis or green tea, it is essential to understand the bioactive substance in the extract.
This type of leaf extract has been used for weight loss and as a cancer-fighting agent for several years.
These extracts are also used in beauty products due to the presence of antioxidants, which protect from harmful ultraviolet radiation (UVR) and provide a toned skin appearance.
The story of its health benefits doesn’t end here, as it also contains substances like L-theanine and caffeine, which help boost our immune system and help release stress and anxiety.
So, let’s explore the advantages of these components while understanding in detail how they work in the human body.
The Role Of L-theanine In Boosting Our Immune System
You might have come to know that Camellia sinensis leaf extract is a great source of L-theanine.
Well, this component is mainly known for the proper functioning of our brain. Besides this, L-theanine is also known to improve the immune system, which leads to the fight against various diseases.
L-theanine is a non-protein amino acid that offers antioxidant and anti-inflammatory effects that help improve immune functions.
Some studies have also proven that L-theanine found in camellia sinensis extract is responsible for producing T-cells. These T-cells are a type of white blood cell (WBC) that are prone to fight against various chronic diseases.
Apart from improving the immune system, these T-cells play a crucial role in combating allergic diseases, infections, and hypersensitivity reactions.
Further, L-theanine decreases the production of inflammatory markers and helps to restore the immunological balance in multiple autoimmune diseases.
At last, the component found in camellia sinensis acts as an anti-viral agent and blocks the virus life cycle in infected cells.
How Does Camellia Sinensis Help To Control Stress And Anxiety?
Apart from L-theanine, Camellia leaf extract also contains caffeine, which is popular for stress release. Let’s first talk about L-theaninee’s contribution to stress release and anxiety control.
Some studies suggest that components like L-theanine play a crucial role in extracting stress effects.
The intake of these components increases dopamine and serotonin in the brain. These two signaling molecules help in the proper functioning of the brain, offer the feeling of happiness, and regulate motivation.
L-theanine found in camellia sinensis leaf or green tea is also associated with calmness and an alert mental state.
According to the research, these components help to increase the production of alpha brain waves, which offers the next level of relaxation.
This relaxation process of L-theanine can be enhanced when combined with caffeine.
When we talk about Caffeine, it is another component that is found abundant in camellia sinensis leaf extract, which is also beneficial for anxiety and stress.
Studies have found that a typical cup of green tea contains about 6% of caffeine, which promotes relaxation. But you need to keep in mind that caffeine is famous for its both positive and negative health effects.
In this regard, many studies suggest that regular intake of caffeine can prevent some serious health issues like type-2 diabetes, cardiovascular diseases, and Alzheimer’s.
It can also improve brain alertness, increase stamina, and improve brain functioning. At the same time, consuming too much caffeine can cause some serious health effects, such as irregular heart rates and many more.
Additionally, caffeine found in camellia sinensis also helps to release dopamine, which provides the feeling of happiness. It empowers the brain to relax at the time of too much stress and promotes calmness from anxiety.
Other than these health benefits, some other potential advantages can gained by consuming green tea or camellia sinensis leaf extract that we have mentioned below.
Other Health Benefits Of Camellia Sinensis Leaf Extract
Besides providing relief from stress and anxiety and improving the body’s immune system, camellia simensis leaf extract also offers some other health benefits.
Other than caffeine and L-theanine, the extract also contains catechines as a primary component, which helps combat diseases like cancer.
The tea leaf extract also contains vitamin B1, lipids, and minerals like magnesium, iron, zinc, calcium, and selenium.
All these components play a crucial role in maintaining the overall health of the individual. In this regard, we have coined some of the potential health benefits that you get from tea leaf extract.
