Nutritional supplements and extracts like Galangal 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 Galangal supplement and why should not take them?

Is it okay to take Galangal 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 Galangal extracts or nutritional supplements may benefit Primary Monoclonal gammopathy of undetermined significance patients on Lenalidomide treatment over Fennel nutritional supplements. But Galangal supplements or Galangal extracts offer less benefit if on Doxorubicin treatment for Primary Non-Hodgkin Lymphoma compared to Baicalin. Similarly, taking nutritional supplements Galangal may benefit healthy individuals who are at genetic risk of cancer due to mutation of gene ERBB2 over Vitamin A. But avoid nutritional supplements Galangal when at genetic risk of cancer due to mutation of gene.

The takeaway being – cancer, genomics, treatments and other personalized factors will influence decision making to questions like: Are extracts or nutritional supplements Galangal beneficial and should not be taken? Why should Galangal be not taken? Who should not take Galangal? What are side effects of Galangal with Doxorubicin chemotherapy? What are the benefits of Galangal for cancer? Can Galangal 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.

Galangal supplement benefits for cancer patients

These are some example questions which nutrition planning should help answer for you. Should you take supplements Galangal? Should you take it when at genetic risk of cancer for mutation of gene ERBB2? Should you take it when at genetic risk of cancer for mutation of gene? Should you take it when diagnosed with Primary Non-Hodgkin Lymphoma? Should you take it when diagnosed with Primary Monoclonal gammopathy of undetermined significance? Should you take it when on Lenalidomide treatment? Should you continue taking it if you change your treatment from Lenalidomide to Doxorubicin? 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 Galangal extracts and nutritional supplements.


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 Monoclonal gammopathy of undetermined significance or Primary Non-Hodgkin Lymphoma, 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 Galangal.

So the question is that are all genetic risks and cancer indications to be considered uniformly when making decisions on the use of Galangal extracts or nutritional supplements? Are the biochemical pathway implications of genetic risk for cancer due to mutation of gene ERBB2 the same as due to mutation of gene? Are the implications of Primary Monoclonal gammopathy of undetermined significance the same as Primary Non-Hodgkin Lymphoma? Is it one and the same if you are on treatment with Doxorubicin or Lenalidomide?

Galangal – An Extract or Nutritional Supplement

Galangal, also known as Thai ginger, Siamese ginger, Galanga, Galangale, Laos, and Blue ginger, is a spicy and pungent tasting root from the ginger family, native to Southern Asia. It is packed with antioxidants and has been used in Ayurvedic medicine and Traditional Chinese Medicine for years. Following are some of the potential health benefits of galangal root:

There isn’t enough research done on the potential side effects of taking high doses of galangal supplements. Some animal studies have shown that excess intake of galangal supplements may lead to serious side effects such as :

  • Diarrhea
  • Lack of appetite
  • Lack of energy, fatigue
  • Frequent urination
  • Coma, and sometimes death

Galangal supplements contain many active ingredients including Pinostrobin and Galangin at different concentration levels. The molecular pathways which are regulated by Galangal include Hypoxia, Oncogenic Cancer Epigenetics and RAS-RAF 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 Galangal individually or in combination is an important decision to be made. When making decisions on the use of supplement Galangal over other nutritional supplements – do consider all these factors.

Who Should not take Galangal Supplements and Why?

There is no easy way to answer the question “For which cancers should I not chooseGalangal nutritional supplements”. Just like the same chemotherapy treatment does not work across patients, for similar reasons Galangal 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 Galangal should be avoided or not and why.

1. Will Galangal Supplements benefit Primary Non-Hodgkin Lymphoma patients undergoing Doxorubicin treatment?

Primary Non-Hodgkin Lymphoma is characterized and driven by specific genetic mutations like TET2, RHOA and CDK12 leading to biochemical pathway changes in Oncogenic Cancer Epigenetics, Cytoskeletal Dynamics and Adherens junction. A cancer treatment like Doxorubicin 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, Galangal supplement should not be taken for Primary Non-Hodgkin Lymphoma along with treatment Doxorubicin. Galangal supplement impacts the biochemical pathway called Oncogenic Cancer Epigenetics 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 Galangal Supplements benefit Primary Monoclonal gammopathy of undetermined significance Patients undergoing Lenalidomide Treatment?

Primary Monoclonal gammopathy of undetermined significance is characterized and driven by specific genetic mutations like LATS2, ZMYM2 and CDK8 leading to biochemical pathway changes in Hypoxia and Hippo Signaling. A cancer treatment like Lenalidomide 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, Galangal supplements should be considered for Primary Monoclonal gammopathy of undetermined significance along with the treatment Lenalidomide. Galangal supplement impacts pathways/processes like Hypoxia which either obstruct drivers of Primary Monoclonal gammopathy of undetermined significance and/or improve Lenalidomide treatment effect.

For Which Cancer to Avoid taking Supplement Galangal?

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 Galangal Supplements for Healthy Individuals with ERBB2 Mutation associated Genetic Risk?

ERBB2 is one of the genes available in panels for cancer risk testing. ERBB2 mutation causes biochemical pathways/processes like RAS-RAF Signaling, Growth Factor Signaling and PI3K-AKT-MTOR Signaling to get impacted. These pathways are direct or indirect drivers of cancer molecular endpoints. Galangal supplements may be considered when the genetic panel identifies mutations in ERBB2 for Esophageal Adenocarcinoma. Galangal impacts pathways/processes like RAS-RAF Signaling and creates a canceling effect in those individuals with ERBB2 mutation.

* Other Factors are also included like BMI, Treatments, Lifestyle Habits

In Conclusion

It is important to remember that cancer chemotherapy treatments and nutrition are never the same for everyone. Food and nutritional supplements like Galangal are chosen by you and can influence outcomes.

“What should I eat?” is a commonly asked question by cancer patients and those at-risk. The answer to this question depends on cancer indication, underlying genetics, current chemotherapy treatments, food allergies, lifestyle information, and food preferences.

The approach to nutrition personalization uses knowledge of active ingredients contained in foods and nutritional supplements, cancer biology, chemotherapy treatment action and genetic mutation prevalence across cancer indications. team of clinicians, clinical scientists and engineers are experts in cancer biology focusing only on nutrition personalization for cancer patients and those at-risk.

What food you eat and which supplements you take is a decision you make. Your decision should include consideration of the cancer gene mutations, which cancer, ongoing treatments and supplements, any allergies, lifestyle information, weight, height and habits.

The nutrition planning for cancer from addon is not based on internet searches. It automates the decision making for you based on molecular science implemented by our scientists and software engineers. Irrespective of whether you care to understand the underlying biochemical molecular pathways or not - for nutrition planning for cancer that understanding is needed.
