Highlights
Nutritional supplements and extracts like Horse Chestnut have benefits and are used by cancer patients and those at-genetic risk of cancer. There is limited or hardly any clinical data available for use of nutritional supplements and foods in cancer patients. Generating clinical evidence of efficacy for cancer through a randomized clinical trial is further infeasible due to variations in genetics and cancer chemotherapy treatments across cancer patients. Hence a different and new approach is needed to find out for which cancers you should not take Horse Chestnut supplement and why should not take them?
Is it okay to take Horse Chestnut extracts or supplements for all cancer indications and any chemotherapy treatment? A common belief but a myth is that everything natural can only be of benefit and do no harm. For example, the use of grapefruit with certain medications is not recommended. Another example is the use of spinach with some blood thinning medications can cause adverse interactions and hence to be avoided. For cancer, nutrition including plant-based foods and supplements can influence outcomes and hence an extremely important decision which needs to be made. Hence NIH-National Cancer Institute has a website for nutrition for cancer care for patients which are generalized recommendations and not personalized for cancer indication and treatments.
A frequently asked question by cancer patients and those at-risk is “What Foods and Nutritional Supplements could be beneficial over others for me?”. “Who should not take an extract or supplement and why?”. Generic guidelines like eating only plant-based-foods or avoiding all sugar or adopting a keto diet is a good start but not actionable and personalized enough.
To find answers to questions on extracts and nutritional supplements and foods requires knowledge of contained active ingredients; genetic mutation prevalence for cancer indication; understanding of underlying cancer biology; chemotherapy treatments and mechanism of actions of active ingredients.
Taking Horse Chestnut extracts or nutritional supplements may benefit Primary Mucinous Cystic Neoplasm patients on Cisplatin treatment over Coconut nutritional supplements. But Horse Chestnut supplements or Horse Chestnut extracts offer less benefit if on Radiation treatment for Primary Sclerosing Epithelioid Fibrosarcoma compared to Astragalus. Similarly, taking nutritional supplements Horse Chestnut may benefit healthy individuals who are at genetic risk of cancer due to mutation of gene BMPR1A over Flaxseed. But avoid nutritional supplements Horse Chestnut when at genetic risk of cancer due to mutation of gene ASXL1.
The takeaway being – cancer, genomics, treatments and other personalized factors will influence decision making to questions like: Are extracts or nutritional supplements Horse Chestnut beneficial and should not be taken? Why should Horse Chestnut be not taken? Who should not take Horse Chestnut? What are side effects of Horse Chestnut with Radiation chemotherapy? What are the benefits of Horse Chestnut for cancer? Can Horse Chestnut help fight cancer and so on.
Whenever there are changes in chemotherapy treatments or cancer tissue genetics – the nutrition may change and hence needs to be re-evaluated. Do consider factors like cancer indication, ongoing chemotherapy treatments and nutritional supplements, age, gender, weight, height, lifestyle and genetics for personalization of nutrition.
Brief Overview
Use of nutritional supplements – vitamins, herbs, minerals, probiotics, and other specialty categories are increasing. Supplements are high concentrations of active ingredients which are also found in different foods. Difference between supplements and foods being that foods contain more than one active ingredient at much lower concentrations. Every active ingredient in an extract or nutritional supplement or food has a unique mechanism of action which can influence nutrition decisions.

These are some example questions which nutrition planning should help answer for you. Should you take supplements Horse Chestnut? Should you take it when at genetic risk of cancer for mutation of gene BMPR1A? Should you take it when at genetic risk of cancer for mutation of gene ASXL1? Should you take it when diagnosed with Primary Sclerosing Epithelioid Fibrosarcoma? Should you take it when diagnosed with Primary Mucinous Cystic Neoplasm? Should you take it when on Cisplatin treatment? Should you continue taking it if you change your treatment from Cisplatin to Radiation? So a general explanation like – it is organic and plant-based or it increases immunity is not sufficient information for making a decision of use of Horse Chestnut extracts and nutritional supplements.
Cancer
Genetic variations across cancer patients can be different and hence no two cancers are alike. The improved availability of “personalized to genetics” chemotherapy treatments and cancer disease monitoring via blood and saliva have been significant factors to improve outcomes. The earlier the lifestyle and treatment intervention – the better the influence on outcome. Genetic testing has the potential to assess cancer risk and susceptibility early. But for at-risk individuals besides regular monitoring in most cases there are no therapeutic treatment intervention options available. After diagnosis with cancer such as Primary Mucinous Cystic Neoplasm or Primary Sclerosing Epithelioid Fibrosarcoma, the treatments get personalized to tumor genomics and factors like staging of disease, age and gender. During cancer remission (after treatment cycle is complete) – monitoring is used for assessment of any relapse and accordingly decide on next steps. A large majority of cancer patients and those at-risk may take nutritional supplements like Horse Chestnut.
So the question is that are all genetic risks and cancer indications to be considered uniformly when making decisions on the use of Horse Chestnut extracts or nutritional supplements? Are the biochemical pathway implications of genetic risk for cancer due to mutation of gene BMPR1A the same as due to mutation of gene ASXL1? Are the implications of Primary Mucinous Cystic Neoplasm the same as Primary Sclerosing Epithelioid Fibrosarcoma? Is it one and the same if you are on treatment with Radiation or Cisplatin?
Horse Chestnut – An Extract or Nutritional Supplement
Horse Chestnut (Aesculus hippocastanum), also known as Buckey, Spanish Chestnut and Conker Tree, is a large deciduous tree, native to the Balkan Peninsula of South East Europe. Horse Chestnut seed extracts may have therapeutic potential. Following are some of the potential health benefits of Horse Chestnut: (M H Pittler and E Ernst, Cochrane Database Syst Rev., 2002; Ireneusz Kapusta et al, J Agric Food Chem., 2007)
- May have anti-inflammatory properties
- May have antioxidant properties
- May help improve subjective symptoms in patients with chronic venous insufficiency having poor blood flow to the veins of the legs
Horse Chestnut supplements contain many active ingredients including Esculin and Aescin at different concentration levels. The molecular pathways which are regulated by Horse Chestnut include Cell Cycle Checkpoints and TGFB Signaling. These biochemical pathways directly or indirectly regulate specific cancer molecular endpoints like growth, spread and death of cancer cells. Because of this biological regulation – for cancer nutrition, the right choice of supplements like Horse Chestnut individually or in combination is an important decision to be made. When making decisions on the use of supplement Horse Chestnut over other nutritional supplements – do consider all these factors.
Who Should not take Horse Chestnut Supplements and Why?
There is no easy way to answer the question “For which cancers should I not chooseHorse Chestnut nutritional supplements”. Just like the same chemotherapy treatment does not work across patients, for similar reasons Horse Chestnut in comparison with other nutritional supplements may be beneficial or not. Along with which cancer and associated genetics – the ongoing treatments, lifestyle habits, height, weight and food allergies are all factors in deciding if Horse Chestnut should be avoided or not and why.
1. Will Horse Chestnut Supplements benefit Primary Sclerosing Epithelioid Fibrosarcoma patients undergoing Radiation treatment?
Primary Sclerosing Epithelioid Fibrosarcoma is characterized and driven by specific genetic mutations like PBRM1, ATRX and PIK3C2G leading to biochemical pathway changes in TGFB Signaling and Inositol Phosphate Signaling. A cancer treatment like Radiation works through a specific pathway mechanism of action. The goal is to have a good overlap between the treatment and cancer driving pathways for a personalized approach which is effective. In such a condition any food or nutritional supplement which has a contrary effect to the treatment or reduces the overlap should be avoided. As an example, Horse Chestnut supplement should not be taken for Primary Sclerosing Epithelioid Fibrosarcoma along with treatment Radiation. Horse Chestnut supplement impacts the biochemical pathway called TGFB Signaling which either promotes drivers of the disease and/or nullifies the treatment effect. Some of the factors which should be considered when choosing nutrition are type of cancer, treatments and supplements being taken currently (if any
2. Will Horse Chestnut Supplements benefit Primary Mucinous Cystic Neoplasm Patients undergoing Cisplatin Treatment?
Primary Mucinous Cystic Neoplasm is characterized and driven by specific genetic mutations like TP53, SPHKAP and IGFBPL1 leading to biochemical pathway changes in Cell Cycle Checkpoints and Apoptosis. A cancer treatment like Cisplatin works through specific pathway mechanisms. The goal is to have a good overlap between the treatment and cancer driving pathways for a personalized approach. In such a condition any food or nutritional supplement which supports treatment action or improves the overlap should be considered. As an example, Horse Chestnut supplements should be considered for Primary Mucinous Cystic Neoplasm along with the treatment Cisplatin. Horse Chestnut supplement impacts pathways/processes like Cell Cycle Checkpoints which either obstruct drivers of Primary Mucinous Cystic Neoplasm and/or improve Cisplatin treatment effect.
Foods to Eat After Cancer Diagnosis!
No two cancers are the same. Go beyond the common nutrition guidelines for everyone and make personalized decisions about food and supplements with confidence.
3. What about Horse Chestnut Supplements for Healthy Individuals with ASXL1 Mutation associated Genetic Risk?
Different companies offer panels of genes to be tested for assessing genetic risk to different cancers. These panels cover genes associated with cancers of the breast, ovary, uterus, prostate, and gastrointestinal system and others. Genetic testing of these genes may confirm a diagnosis and help guide treatment and management decisions. Identification of a disease-causing variant may also guide testing and diagnosis of at-risk relatives. ASXL1 is one of the genes generally available in panels for cancer risk testing.
ASXL1 mutation causes biochemical pathways/processes like Cell Cycle Checkpoints, Oncogenic Cancer Epigenetics and Suppressive Histone Methylation to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Horse Chestnut should not be taken when the genetic panel identifies mutation of ASXL1 for Chronic Myelomonocytic Leukemia. Horse Chestnut impacts pathways/processes like Cell Cycle Checkpoints and creates adverse conditions with ASXL1.
4. What about Horse Chestnut Supplements for Healthy Individuals with BMPR1A Mutation associated Genetic Risk?
BMPR1A is one of the genes available in panels for cancer risk testing. BMPR1A mutation causes biochemical pathways/processes like TGFB Signaling to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Horse Chestnut supplements may be considered when the genetic panel identifies mutations in BMPR1A for Colon Cancer. Horse Chestnut impacts pathways/processes like TGFB Signaling and creates a canceling effect in those individuals with BMPR1A mutation.
