Functional Medicine


Functional Medicine

What makes our Functional Medicine program different?

We combine both Functional Medicine with Oriental Medicine from our experienced practioners to address the root cause of disease so the patients health and immune system becomes stronger by reducing inflammation and eliminate issues that may be contributing to your body's dysfunction.

What do we treat and how do we treat it?

As the clinic for Functional Medicine Naperville trusts, we use a variety of treatment methods to restore health and minimize or eleminate the need for medications. We treat a wide variety of conditions from thyroid disorders, pain conditions, and autoimmune diseases. See the list below of conditions we have helped with our functional medicine program combined with Oriental medicine at The Emperor's Medicine.

When we meet a patient, we answer these four questions:

1) “What is wrong with me?”

2) “Can you help me?”

3) “How long would it take?”

4) “How much does it cost?”.

Once you enroll with us (if we believe that we can help you), we discuss with you your step by step plan. Perhaps the best part is that the treatment programs uses natural methods, so they are safe while being very effective.

But most of all, we treat people. We treat their conditions and health problem but always do it holistically, keeping the whole person in mind.

We work to build health so that disease states improve, by helping the body to heal we can harness the self-healing capability of the human body. We are happy to communicate with other practitioners as you build your health care team.

A sensible approach that seeks the best outcome for our patients is what we consider to be our ‘Integrated Medicine’ – medicine that integrates the best therapies for the good of our patients.

We specialize in treating and correcting the underlying causes of diseases, not just the symptoms. We can focus on causes and remedies by using thoughtful comprehensive evaluation and analysis.


Assess the patient using in-depth methods

We do a thorough history of your issues including what the previous doctors has diagnosed but we go beyond that. There are many systems involved when a patient has some disease process, not just one body part. For example, if someone has lupus it is important to figure out if the digestive system is a potential contributing system. We use blood work, sophisticated software programs, and in-depth assessment questions.

Identify and Treat the Cause

Symptoms of the disease are the tip of an iceberg. The disease itself lies below the waters. If we treat only symptoms than we are not making people well. For example, in infections, fevers are a symptom and not the disease. In fact, fever is a response by the body to improve our ability to fight the infection. But when the cause is identified, perhaps the bacteria of Lyme disease then we put together a personalized treatment program. We often use acupuncture, nutritional supplements, detoxification methods, and dietary approaches. Dr. Tennant is one of the few doctors in the area that is Certified in Functional Medicine.

Treat the Whole Person

By observing your unique individual patterns of symptoms and your genetics we can understand the unique strengths and weaknesses of your body and how to best support you. For example, research has shown that people with asthma who have blue eyes have a different biological reaction driving the symptoms as compared to a person with brown eyes. The symptoms look the same on the surface but are actually quite different underneath.

Doctor as Teacher

Education is always a part of your care. Our patients learn about health and how to cultivate health. Many patients, as they take treatments and become healthier, educate others in their community of families and friends. Some patients so dramatically improve that they become beacons of health that are sought out to explain how they have regained their health.

Preventive Medicine

Prevention is not just a blood test or annual physical. It is actively taking part in cultivating and building health, it is a responsibility to ourselves we all have. Functional medicne and Oriental medicine treatments incorporate this principle by strengthening the body.

The Healing Power of Nature

We are a part of nature and an abundant creation provides a tremendous wealth of powerful healing agents. Our bodies always possess self-healing capabilities and our duty as physicians and health practitioners is to strengthen and improve these mechanisms of innate healing. So, in essence, in functional and natural medicine, we look to find pathways and levers to move your body from not functional well (disease) to that of one of health and relief of symptoms. That is our focus, our training, and our experience.

Doctor wanted to “Kill my thyroid”!

I was told in 2011 that my TSH level was .5 and I would need to have radiation therapy on it. This was to attack the one nodule that I had and there was a chance that it would attack the whole thyroid and render it useless. Then I would be on hormone pills for the rest of my life. I refused and never went back to him. I had no symptoms of hyperthyroidism and I was not going to do that. Fast forward 7 years and my TSH level started to drop even more and now I had 6 nodules. I still had no symptoms but I knew I had to do something. I went to a different Endocrinologist and she basically told me the same thing and had no other option. My prayer was to find a different solution, so I searched the internet and found The Emperors Medicine. Dr. Gary told me that he had an 80% success rate with women in my situation. All he needed was 90 days of a 6 month regimen of detoxes, supplements and acupuncture and he would be able to tell if he could help me. And it is all natural. I was all in!! I had to try! Now it has been just over 2 months and with Dr. Gary and Dr. Selma my TSH level is higher than it has been in 8 years. We are still going and I have more energy and feel great. Thank you, Lord Jesus for bringing me here and Thankyou Dr. Gary and Dr. Selma for your gentle care.

"Both Dr. Selma and Dr. Gary saved my life. Not only did they share the vision that HEALING the thyroid is possible, but as a team they also carried out the goal by showing me it is ATTAINABLE. I am beyond grateful that I found them and am happy to say I am off of thyroid medicine and feeling much better. This was done in a natural way which compliments your natural physiological make-up, absolutely zero drugs. The importance of feeding and nourishing your body is emphasized, as well as the modality of acupuncture which has worked for thousands of years. If you have any auto-immune disorders, know that it can be healed and you can have a wonderful quality of life."

Thank you The Emperor’s Medicine!


Thyroid Problems Gone

"Hi, Hello everyone! I’ve made much much progress here with my hypothyroidism. And thanks to Selma and Dr. Tennant, my future, my healthy future is here. This actual acupuncture and functional medicine clinic features some of the most intelligent, caring people and a great massage therapist. A great friend recommended this place to me and to pay it forward I want to say that I am confident that The Emperor’s Medicine will be your next favorite place too."

Could you tell us how were you feeling before you came to The Emperor’s Medicine?

I was tired all of the time, very sluggish, I had no energy to move around. Emotions were up and down, a little bit of anxiety, a little bit of depression, when I lay down to go to sleep, I couldn’t go to sleep. I just could not function properly and I knew that something was wrong. The panels that were given to me by my original doctor did not cover everything and I felt that we needed something more.

How are you feeling now?

Lots more energy, better sleep! I’ve improved greatly, I’m less emotional, more supportive and more looking forward to my future.
