Cimicifuga-Petasites Extract Combination for Synergistic Anticancer Therapy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical treatments for cancer lack effective and safe alternatives that can provide both therapeutic and prophylactic benefits.
Innovation Solution
A combination of extracts from Cimicifuga species and Petasites species, specifically Cimicifuga racemosa and Petasites hybridus, is used to create a medicament for the therapeutic or prophylactic treatment of cancer, leveraging synergistic effects demonstrated in a human erythroleukemia cell line with the JAK2V617F mutation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional cancer treatments are used, then therapeutic effect is achieved, but safety and side effects worsen
Solution Approach 1:
The patent combines extracts from two different plant species (Cimicifuga and Petasites) to create a composite herbal medication. This composite approach leverages synergistic effects between the plant compounds to enhance anti-cancer activity while maintaining a favorable safety profile, as evidenced by the combination index analysis showing synergistic rather than additive effects.
Solution Approach 2:
The patent optimizes the dosage parameters of the extract combination, specifically establishing a dosage range of 0.5-5 mg per kg body weight per day. By carefully controlling the concentration and dosage parameters, the treatment achieves effective cancer cell inhibition while minimizing toxic side effects, as demonstrated by the therapeutic window identified in clinical studies.
2Device complexity
If single plant extracts are used, then treatment simplicity is maintained, but therapeutic efficacy is limited
Solution Approach 1:
The patent merges extracts from two distinct plant species (Cimicifuga racemosa and Petasites hybridus) into a single combined medication formulation. This merging strategy creates synergistic interactions between the plant compounds, producing enhanced anti-cancer effects that exceed the sum of individual extract activities, as demonstrated by combination index values less than 1.0 indicating synergism.
Solution Approach 2:
The combined extract formulation serves multiple therapeutic functions simultaneously: it exhibits anti-proliferative effects against cancer cells, induces apoptosis in malignant cells, and modulates signaling pathways involved in cancer progression. This multi-functionality is achieved through the diverse phytochemical constituents of the plant combination acting on multiple molecular targets.

AI summary
The present invention is directed to the novel use of an extract combination comprising extracts from a Cimicifuga species, e.g. Cimicifuga racemosa (also termed Actaea racemosa L; black cohosh) and a Petasites species, e.g. Petasites hybridus, for the therapeutic or prophylactic treatment of cancer. Also, the invention pertains to the use of such extract combinations for preparing a medicament, corresponding pharmaceutical compositions, comprising a combination of an extract from Cimicifuga sp. and an extract from Petasites sp., as well as a method for the therapeutic or prophylactic treatment of cancer, preferably by oral administration of the extract combination or pharmaceutical composition.
