History of Glandular Therapy
From ancient organotherapy to modern supplements — exploring over a century of thyroid glandular use.
A Legacy of Natural Healing
The use of animal glandular tissue to support human health has a rich and fascinating history stretching back thousands of years. What began as ancient intuition has evolved through scientific discovery into the modern glandular supplements we know today.
Understanding this history helps us appreciate how Thyrovanz continues a tradition that has been refined over more than a century of medical and nutritional science.
Key Milestones in Thyroid Therapy
Origins of Organotherapy
For centuries, traditional medicine systems around the world used animal organs to treat ailments. The concept was based on the intuitive idea that consuming a healthy organ could restore function to a diseased one. Ancient physicians in China, Egypt, and Greece all documented the use of animal tissues as treatments.
The Dawn of Modern Thyroid Therapy
English physician Dr. George Murray made medical history when he successfully treated a patient suffering from severe hypothyroidism (myxedema) by injecting an extract made from sheep thyroid glands. This breakthrough demonstrated for the first time that thyroid tissue could effectively restore thyroid function in humans.
The Era of Desiccated Thyroid
Following Murray's breakthrough, oral preparations of desiccated thyroid extract (DTE) were developed, typically made from dried and powdered pig thyroid glands. For over 60 years, DTE was the standard and only effective treatment for hypothyroidism, helping millions of patients worldwide.
The Rise of Synthetic Hormones
Scientists successfully synthesised the thyroid hormone T4 (levothyroxine) in the laboratory. This synthetic version offered a stable, pure, and predictable dose. Backed by pharmaceutical marketing and new understanding of T4-to-T3 conversion, levothyroxine became the new standard of care by the 1970s.
The Natural Resurgence
In recent decades, renewed interest in natural and holistic health has brought attention back to glandular supplements. Thyrovanz represents the modern evolution of this tradition — combining New Zealand sourcing, freeze-dried processing, and flexible dosing with the heritage of over a century of glandular therapy.
