Herbal Cognitive Agent Using Jujube Seed and Sweet Flag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current anti-dementia drugs fail to effectively maintain or improve cerebral functions, promote nerve cell repair, induce neurogenesis, or remove dementia-causing proteins, and there is a need for preventive medications that are safe, affordable, and can be self-administered to prevent neurodegenerative diseases like Alzheimer's, frontotemporal dementia, and Lewy body dementia.
Innovation Solution
Utilizing jujube seed and the stem portion of Japanese sweet flag in specific forms, such as crushed products, extracts, and extraction residues, to develop agents that address the technical problem by improving cerebral functions, promoting nerve cell repair, inducing neurogenesis, and removing dementia-causing proteins.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional anti-dementia drugs are used to suppress or remove dementia-causing proteins, then protein accumulation may be reduced, but clinical efficacy is insufficient and most drug candidates fail to demonstrate expected effects in clinical trials
Solution Approach 1:
The patent changes the chemical parameters from conventional synthetic drugs to natural herbal compounds (jujube seed extract and Japanese sweet flag extract). This parameter change enables the agent to effectively remove dementia-causing proteins (Aβ, tau, α-synuclein) while improving clinical efficacy without the failures seen in conventional drug development
Solution Approach 2:
The patent uses a composite herbal formulation combining jujube seed extract and Japanese sweet flag extract. This composite material works synergistically to address multiple pathological mechanisms simultaneously - removing protein aggregates, reducing inflammation, and protecting nerve cells - thereby achieving reliable clinical efficacy that single-target drugs cannot achieve
2Ease of operation
If preventive medications are developed to be safe and affordable for self-administration, then accessibility improves, but effectiveness in maintaining or improving cerebral functions and removing dementia-causing proteins must be maintained
Solution Approach 1:
The patent employs natural herbal extracts from commonly available plants (jujube seed and Japanese sweet flag) that can be produced affordably and administered orally. These natural compounds provide sustained protective effects when taken regularly, enabling safe self-administration while maintaining effectiveness in preventing neurodegenerative diseases through multiple mechanisms including protein removal and neuroprotection
3Reliability
If agents are designed to promote nerve cell repair and induce neurogenesis, then nerve cell regeneration is enhanced, but the complexity of achieving multiple effects (protein removal, neuroprotection, neurogenesis) simultaneously increases
Solution Approach 1:
The patent employs herbal compounds that exhibit multi-functionality, simultaneously achieving multiple therapeutic effects: removing dementia-causing proteins (Aβ, tau, α-synuclein), reducing neuroinflammation, protecting existing nerve cells from damage, and promoting neurogenesis. This universal approach through natural compounds simplifies the overall treatment strategy compared to using separate targeted therapies for each mechanism
