Tulsi lowers cholesterol by reducing levels of LDL and triglycerides without suppressing essential bodily functions. It also elevates levels of HDL cholesterol, contributing to vascular well-being and assisting in the removal of excess fat.

What is Tulsi Holy Basil?

Ocimum sanctum, or what you might recognize more readily as Tulsi, comes from the Labiatae family. Tulsi goes by various names. In Sanskrit, it's referred to as Vishnu-Priya; in Hindi, Kala-Tulsi; and in English, India's Holy Basil. But these are more than just monikers; they're connections to a rich tapestry of belief and reverence. Hindus connect it to the figure of a goddess and its name means “the incomparable one”. 

Yet, this herb is not confined to ritualistic domains; it's a staple in Ayurvedic medicine. It's not just the leaves but also the seeds and the root of Tulsi that have found their place in healing practices.

When we peer into the chemical composition of Tulsi, we're faced with a realm of complexity. This small herb is packed with a range of nutrients and biologically active compounds, the nature of which can shift based on time, cultivation, and storage.

And this complexity has made the standardization of Tulsi's active components a rather intricate affair. However, researchers have managed to identify and extract several elements, such as eugenol—an essential oil—and ursolic acid.

Science has not remained a bystander in the story of Tulsi. Numerous studies have explored the pharmacological impacts of different Tulsi extracts on various physiological systems. This herb has shown influence from the immune to the reproductive, from the central nervous to the cardiovascular. Tulsi is often regarded as a vitalizer, an enhancer of physical endurance. [1]

How is Tulsi consumed? The tradition offers a wide array, from cold, hot, or dried leaf tea to powdered leaf, alcohol tinctures, oil preparations, and even formulations using the seed, root, and stem. 

What we find in Tulsi is more than an herb; it's a confluence of science, tradition, and spirituality. Its complexity is not just chemical but cultural, and its benefits reach far beyond what we can measure in a lab.

How Holy Basil Works in the Brain

Holy Basil might seem a modest herb, but its impact on the brain represents an intellectual fascination that transcends mere botany. Here we encounter two particular features that compel our attention.

First, consider the issue of chronic loud noise. This is not just a matter of urban inconvenience; it has been identified as a significant threat to public well-being. It's easy to overlook the profound damage that noise can cause beyond our auditory senses. But the assault on our hearing can extend to the heart, the endocrine system, and even the nervous system itself.

The noise doesn't simply affect the quality of our environment; it invades our very biology, damaging DNA, suppressing neurotransmitters, and undermining the immune system's defenses. [2] But Holy Basil seems to offer a shield against this cacophony. The herb's ability to protect the brain from the onslaught of chronic noise is not only remarkable but scientifically verified.

Researchers found that a 70% extract of Holy Basil maintained neurotransmitter levels from noise stress. [3] What was just a plant becomes a sort of biological armor against an environmental hazard.

Holy Basil and Memory

Now, let's turn to the cognitive realm, where Holy Basil has shown its capacity to protect and enhance memory. Specifically, it has been demonstrated as an inhibitor of acetylcholinesterase (AChE), the enzyme that aids in the breakdown of acetylcholine in the brain. [4]

An excess of AChE can suppress acetylcholine, leading to the degradation of learning and memory, and it has particular relevance to neurodegenerative diseases like Alzheimer's. Japanese researchers found that both water-based and alcohol-based extracts of Holy Basil significantly decreased (AChE)activity, suggesting a real potential in managing cognitive dysfunction. [5]

Holy Basil and Stress

Stress is not merely a buzzword of modern living; but a complex biochemical process that has the potential to unmake us. Our ability to grasp its true nature, and harness its insidious effects, is among the most pressing challenges of our time.

The brain functions using a delicate balance where cells signal, neurotransmitters communicate, and hormones play their part. The body's immediate response to stressors is typically healthy. The "fight or flight" response elevates heart rate and blood pressure through catecholamine neurotransmitters such as dopamine and norepinephrine.

But what happens when stress becomes persistent and endures beyond the passing threat? That's when chronic stress mounts an attack on our well-being, hijacking our bodies' natural equilibrium. An alarming 75 to 90 percent of all human diseases were linked to this invisible adversary. [6]

The consequences of chronic stress are far-reaching:

- Chronic inflammation

- Cardiovascular disease

- Metabolic disturbances like diabetes

- Neurodegenerative afflictions, including anxiety, depression, Alzheimer's, and Parkinson's

That's when Holy Basil comes into play. The mechanisms of its action are manifold and elegantly intricate:

  • It's an adaptogen, meaning it can assist the body in restoring balance following stress.
  • It may support healthy cortisol levels, a hormone whose overabundance during stress can impair memory and lead to weight gain, anxiety, and depression. [7]
  • It elevates neurotransmitters associated with learning, memory, and relaxation. [4]
  • It contains anti-inflammatory, antioxidant, and neuroprotective compounds, which can shield the brain from damage. [8]

Several studies lend credence to these claims. In one study with 158 people between 18 and 65 years old, they tested something called OciBest, a unique extract from the Tulsi plant. This extract was a whopping 1.6 times (or 39%) better at helping with stress than a placebo, all across six weeks. [9]

In another study with 35 people dealing with anxiety, taking tulsi twice with meals helped reduce stress in just two months. [10]

Other Notable Benefits

1. Tulsi Boosts Immunity

The immune system is our body's intricate defense network that recognizes and annihilates germs, safeguarding us from infection. But even the most complex machinery can benefit from an ally.

Here is where Tulsi enters the narrative. This plant serves as a veritable companion to our immune system. When consumed on an empty stomach, Tulsi leaves enhance immunity—a wisdom passed down through generations, now being explored and affirmed by modern science.

Through a meticulous study involving 24 healthy participants, the daily consumption of tulsi leaf extract exhibited noteworthy effects. After four weeks of consistent intervention, significant enhancements were observed in crucial components of the immune system, including IFN-y, IL-4, T-helper cells, and natural killer cell activity. This surge in immune activity underscores the potential immune-boosting properties of tulsi. [11]

Moreover, an intriguing facet emerges as tulsi seems to influence both the Th1 and Th2 immune responses. This balanced modulation indicates tulsi's ability to play a role in maintaining equilibrium within the immune system, fostering a comprehensive immune response.

Furthermore, Tulsi seed oil offers another dimension to this relationship. It influences neurotransmitters that play a vital role in immune system activation. [12]

2. Tulsi Decreases Blood Sugar

According to meticulous research, Tulsi's leaves possess the extraordinary ability to substantially reduce blood glucose levels. But this is not a mere mechanical intervention; it's a symphony of molecular interactions, where Tulsi's antioxidant properties seek and neutralize the restless wanderers known as free radicals. [13] This harmonious interplay contributes to Tulsi's antidiabetic effect.

3. Tulsi Lowers Cholesterol

Cholesterol, a molecule with a dual nature, strides a fine line between friend and foe. In its two distinct forms—LDL, the so-called "bad" cholesterol, and HDL, its "good" counterpart—it either nourishes or imperils us, bestowing vitality or sowing the seeds of future diseases. High levels of LDL with triglycerides can propel us toward the grim specters of heart disease and stroke.

Enter Tulsi leaves. Their gentle intervention has been found to moderate this treacherous dance of lipids. Research has illuminated Tulsi's ability to diminish cholesterol, reduce the threatening presence of LDL and triglycerides, and do so without suppressing the body's own life-sustaining functions.

But Tulsi does not merely subtract; it also adds, elevating the levels of HDL, the guardian of our vascular well-being. Simultaneously, Tulsi assists in ushering excess fat out of the body. [14]

Safety and Side Effects

Are you thinking about adding holy basil or other supplements to your diet? That's a choice many people are considering. Let's break it down into simple, actionable steps, so you know what to do.

  1. Talk to Your Doctor First: It's always a good idea to check with your healthcare provider before trying something new. They know your health situation and can give you personalized advice.
  2. Be Careful with Certain Groups: Right now, there's not enough information to say it's safe for infants, children, or pregnant or breastfeeding women to take holy basil. So it might be best for these groups to avoid it for now.
  3. Consider Potential Side Effects: Even though no major side effects have been found it's still important to be cautious. Avoid Holy Basil if you're lactating, pregnant, or trying to conceive.

The Bottom Line

Holy basil is not merely a staple in culinary traditions but a potentially powerful ally for our health. Its promising abilities to lower blood pressure, blood sugar, and cholesterol paint a picture of a herb with diverse and meaningful applications.

Additionally, the suspected contributions to enhancing memory and supporting the immune system further elevate its standing. While these effects warrant further scientific exploration, the multifaceted nature of holy basil extends beyond the kitchen, offering a glimpse into a botanical world rich with potential.
