Are Ginkgo Biloba Leaf Tablets and Ginkgo Biloba Extract Tablets the same?

Generally speaking, Ginkgo biloba leaf tablets and Ginkgo biloba extract tablets are not exactly the same; they differ in aspects such as component purity, drug standards, precision of pharmacological effects, dosage form stability, and suitable populations. The specific differences are analyzed below:

1. Component Purity

The main component of Ginkgo biloba leaf tablets is Ginkgo biloba extract, but it may also contain some other substances, such as minor impurities originally present in the Ginkgo leaves. Its production process is relatively simple, and the level of extraction and purification of Ginkgo leaves is not as high as that of Ginkgo biloba extract tablets. In contrast, Ginkgo biloba extract tablets undergo a more refined extraction process, resulting in relatively higher purity of active ingredients. They mainly contain active components such as ginkgo flavonoid glycosides and terpene lactones, with lower levels of impurities and more precise and defined composition, enabling more precise pharmacological effects.

2. Drug Standards

The pharmaceutical standards followed by Ginkgo biloba leaf tablets may be relatively broad, with quality control mainly ensuring the basic content of Ginkgo biloba extract meets certain requirements. In contrast, Ginkgo biloba extract tablets typically adhere to higher quality standards, with more precise specifications for the content and purity of active ingredients and limits on impurities. This ensures the efficacy and safety of the drug, as its composition is relatively uniform, and therefore the standards place greater emphasis on quality control of effective components.

3. Precision of Pharmacological Effects

Due to their relatively complex composition, Ginkgo biloba leaf tablets may have pharmacological effects influenced not only by the main active ingredients but also by other components. In contrast, Ginkgo biloba extract tablets, with their higher component purity, have more precise pharmacological effects primarily focused on the improvement of blood circulation, antioxidant effects, and others associated with active ingredients such as ginkgo flavonoid glycosides and terpene lactones.

4. Dosage Form Stability

Due to their relatively complex composition, Ginkgo biloba leaf tablets may be affected by multiple factors during storage. For example, some components may react with oxygen or moisture in the external environment, leading to slightly reduced drug stability and possible changes in the content of active ingredients over time and under different storage conditions. In contrast, after purification, Ginkgo biloba extract tablets demonstrate relatively better dosage form stability. Under appropriate storage conditions, the active ingredients can remain stable for a longer period.

5. Differences in Suitable Populations

Ginkgo biloba leaf tablets are more suitable for patients with relatively mild symptoms who do not require high precision of drug components. On the other hand, Ginkgo biloba extract tablets are better suited for individuals who require high drug precision and aim to treat diseases using highly purified active ingredients.

Regardless of whether Ginkgo biloba leaf tablets or Ginkgo biloba extract tablets are used, they should be purchased from legitimate sources to ensure drug quality and avoid counterfeit or substandard products that may affect efficacy or even harm health. Additionally, do not arbitrarily adjust the dosage or switch medications without guidance. It is recommended to use medications rationally under the guidance of a qualified physician to ensure safe and effective medication use.
