Allergy Treatment in Greenville, SC
Allergy Treatment at IHP Greenville — TCM, in-house herbal pharmacy, functional medicine. Dr. Hendry, DAOM. Call (864) 365-6156.
An immune system producing seasonal allergy responses to tree pollen that were mild ten years ago and are now debilitating hasn't been exposed to more pollen — the gut barrier integrity, vitamin D status, and T-regulatory cell function that used to keep the Th2 response in check have deteriorated. I treat allergies as an immune dysregulation problem with measurable upstream drivers. Vojdani's research on intestinal hyperpermeability, Aranow's work on vitamin D's role in T-regulatory cell function, and the acupuncture evidence for Th1/Th2 rebalancing together define a treatment strategy that reduces sensitization rather than just suppressing each reaction.
How Allergy Treatment Works
Allergy treatment combines acupuncture (which modulates Th1/Th2 immune balance, reduces IgE production, and relieves acute allergic symptoms), Chinese herbal medicine (particularly Yu Ping Feng San — Jade Screen — the classical allergy prevention formula with confirmed immunomodulatory properties), and functional medicine assessment of immune dysregulation drivers.
Conditions Treated with Allergy Treatment
Immune Regulation vs. Antihistamines and Allergy Shots for Symptom Suppression
Allergen immunotherapy and antihistamines are clinically validated tools, and we do not dismiss their utility. What they address is downstream immune reactivity, not the upstream conditions that caused immune polarization to shift in the first place. Consider a 44-year-old woman who has been on loratadine daily for six years and completed a three-year subcutaneous immunotherapy course for tree pollen. Her seasonal symptoms are moderately controlled, but she has developed new sensitivities to four foods that were not on her original panel. Serum 25-OH vitamin D measures 18 ng/mL. Intestinal permeability markers show elevated zonulin. Microbial diversity is low by stool analysis. Without correcting the Treg-permissive conditions, the immune system continues generating new sensitizations to replace those desensitized by immunotherapy. Our protocol repairs the gut epithelial barrier, repletes vitamin D to a functional range of 50-70 ng/mL, restores fiber-driven butyrate production, and applies acupuncture to down-regulate sympathetically driven mast cell activation. This upstream reset reduces the rate of new sensitization formation rather than simply suppressing each reaction as it appears.
Research & Evidence
Allergic disease represents a shift in immune polarization toward a Th2-dominant pattern, characterized by elevated IgE production, mast cell sensitization, and eosinophilic infiltration of mucosal tissues. Aranow (J Investig Med. 2011) demonstrated that vitamin D receptors are expressed on dendritic cells and T-regulatory cells, and that vitamin D deficiency impairs the Treg-mediated suppression of both Th1 and Th2 responses, creating permissive conditions for allergic sensitization. Vojdani (Autoimmune Dis. 2014) documented that increased intestinal permeability allows dietary and environmental antigens to cross the mucosal barrier and prime systemic immune responses, making gut barrier integrity a central lever in allergic disease management. The Sonnenburg lab (Cell. 2016) established that low dietary fiber intake reduces microbial short-chain fatty acid production, directly reducing butyrate-driven Treg differentiation in the gut-associated lymphoid tissue. Our approach combines IgE and IgG food panel testing, serum vitamin D 25-OH quantification, gut permeability markers, and acupuncture protocols documented to modulate mast cell degranulation and restore Th1/Th2 balance through autonomic nervous system regulation.
Your First Appointment
Describe your allergy pattern — seasonal vs. perennial, environmental vs. food, severity, and any prior allergy testing. Bring prior allergy lab results (IgE panel, skin prick test results, food sensitivity testing). Current allergy medications are relevant for interaction screening.
Why Dr. Hendry for Allergy Treatment
Dr. Hendry's functional medicine training in gut-immune axis biology allows him to address the intestinal permeability and immune dysregulation that drive allergic sensitization — a root-cause approach that conventional allergy management does not take.
