No More Eye Drops EVER

Maximize Your Tears By Supporting Your Parasympathetic Nervous System!

Have you tried everything to keep your eyes moist? Eye drops, eye ointments, and even punctal plugs boost moisture or try to retain moisture, but they do not address the underlying causes of low tear production. Therefore, these products are limited in what they can do for you. When tear production is not optimal, these products do nothing to support the systemic (body-wide) process resulting in less-than-optimal tear production.

How Is Tear Production A Systemic Process? First, Let’s Look At How Tears Are Formed.

Your lacrimal gland produces the bulk of your tears. The lacrimal nerve signals the lacrimal gland to produce tears whenever you need them. This is part of your Parasympathetic Nervous System (the same system of the body that allows you to rest, to calm yourself, and to digest food). The lacrimal nerve communicates with the lacrimal gland via a chemical messenger called acetylcholine.

The lacrimal gland receives the signal that you need more tears. It then releases acetylcholine (the chemical messenger) which immediately instructs the lacrimal gland to pump out tears, resulting in increased moisture!

When acetylcholine levels are low for any reason, or if the lacrimal nerve isn’t releasing acetylcholine sufficiently, tear production goes down.

⇨   Keeping your eyes moist is one of the primary functions of your Parasympathetic Nervous System.


So Why Does Your Parasympathetic Nervous System Need Support?

The release of acetylcholine declines with age and inflammation.  And sometimes our diet and our genes make it harder for us to produce enough acetylcholine. When this happens, the parasympathetic nervous system is less efficient, and tear production declines.

What Else Does The Parasympathetic Nervous System Support?

The parasympathetic nervous system supports relaxation. It calms the body, allows a slower heart rate, slows down rapid breathing, and allows us to recover from stress.

The parasympathetic nervous system also supports every aspect of proper digestion, from swallowing and motility (movement of food and stool throughout your digestive tract) to normal stomach acid production, gallbladder function, and pancreatic function. These organs are critical for optimal digestion of nutrients.

Additionally, your parasympathetic nervous system is the anti-inflammatory pathway of the body. Although some inflammation is good (and even necessary for recovery from illness or injury), chronic inflammation can be problematic — the parasympathetic nervous system (via the vagus nerve) helps retain the proper balance of inflammation.

How Does Inflammation Affect Ocular Moisture?

Inflammation (of the eyes or of the body in general) can limit the release of acetylcholine, thus resulting in less than optimal tear production. By supporting the parasympathetic nervous system, tear production is maintained in two ways:

    1. Direct support of the lacrimal nerve to allow normal tear production.


  1. Indirect support by balancing the inflammation that limits tear production (via support of the vagus nerve).


How Can You Safely Support Your Parasympathetic Nervous System?

POTS Medication, POTS Treatment, POTS Clinic, POTS Recovery, POTS Parasym Plus, POTS Soothing Digestive Aid, POTS Digestive Enzyme, POTS Thera pH, Beta Balance, Beta Balance B-12 MC Spray, Vagus Nerve Support, Vagus Nerve Support Digsetive Enzymes, Vagus Nerve Support Soothing Digestive Aid

Parasym Plus™ is a patented product designed to support your parasympathetic nervous system. It is patented because it (uniquely) stimulates the vagus nerve while it supports acetylcholine needed for normal tear production.

Parasym Plus™ was developed by an eye doctor, Diana Driscoll, OD after heavily researching the role of the autonomic nervous system in tear production.




What Else Does Parasym Plus™ Do?

Parasym Plus™ supports every aspect of digestion by supporting the vagus nerve. Your vagus nerve allows proper stomach acid production, normal gallbladder function as well as pancreatic function, and it allows proper motility (movement of food and stool) throughout your digestive tract.

Parasym Plus™ also provides what the vagus nerve needs to slow a rapid heart, calm breathing, and allow us to relax.

Importantly, Parasym Plus™ crosses the blood-brain barrier to support acetylcholine for the brain (the major neurotransmitter needed to think sharply and create short-term memories).

Parasym Plus™ is patented because it is unique. No other product can do what Parasym Plus™ can do.
