Top 7 Recommendations

I realize many people just want the bottom line.  Here it is:

All of these can be combined, but start by taking one at a time for a few days before you start stacking.

Supplements/Methods To Decrease Both Th1 and Th2

Supplements that increase IL-10 will decrease both kind of T cells (R).

Decreasing Inflammation By Inhibiting CD26, CD40, CD80, CD86, MHC

inflammation_233859859

CD26, CD40, CD80, CD86, and MHC are molecules on T helper cells, dendritic and other immune cells. These proteins are stimulatory and activate T helper cells (R).  Decreasing them should help inflammatory conditions regardless of Th1/Th2 dominance.

The more these costimulatory signals cause the division of T cells, the more likely they are then to become ‘dormant’. (R)

By inhibiting these molecules, you also inhibit the maturation of dendritic cells (R).  When these cells mature they become harmful.

Interleukin-10 has (1) immunosuppressive effect and (2) immunostimulatory effect. It down-regulates the expression of Th1 cytokines, MHC class II antigens and co-stimulatory molecules on macrophages.

There’s lots of contradictory information on zinc, but overall I am for supplementation unless you’re eating a lot of organ meat.   Zinc has been shown to be beneficial in animals with higher than RDA levels and is especially important for the elderly (R).  Zinc is also a good cancer preventative (R).  Too much isn’t good, though.

Supplements That May Balance Th1/Th2 Immune System

  • Grape seed extract (R)****Contradictory (R) -probably balancing
  • Pine bark (R) – likely has the same effect as GSE
  • Eleuthero/Siberian ginseng. A study shows it decreases cytokines that create Th1 and Th2 cells in healthy people (R), but a cellular study shows that it increase cytokines that are released by Th2 cells (R).  It’s probably immune balancing.
  • Baicalin/Chinese Skullcap (R)
  • Rooibos(R).  This has mixed effects and probably balances Th1/Th2
  • Tribulus (R1+R2)

Be Wary: Supplements/Methods That Increase Both Th1 and Th2

  • Thyroid hormones (R).  I can confirm this through  experimentation.  When my thyroid hormone levels are higher, the inflammation I get from a food I’m intolerant to goes up 2-3 fold.
  • Elevated IGF-1 (RR2).  IGF-1 is elevated by insulin secretion and amino acids like BCAA’s, leucine, methionine, lysine and tryptophan (R).  Contradictory (R)
  • Dairy (Bovine serum albumin, β-Lactoglobulin) (R)
  • Ozone (R)
  • Asian Ginseng (R) – Mostly stimulating, but also regulating.  Ginseng has many compounds in it and the effects are complex and depend on dosage and other factors, but it seems to increase both systems in response to many types of immune challenges, even innocuous ones.
  • Tulsi (R)
  • Tocotrienols (R)
  • Bacopa (R)
  • Rhodiola (R)
  • Echinacea (R)* -contradictory, probably only increases Th2.
  • Tart Cherry (R)
  • Aloe (R) – (increases IL-1, IL-6, and TNF-α in cancer cells)
  • Almonds – specifically the skin (R)
  • Asparagus Racemous (R)
  • Licorice (R) – but eventually downregulates it because of glucocorticoids.
  • Goji Berries (R) (increases IL-12, TNF, IL-1b, Nf-kB, AP-1, CD40, CD80, CD86 and MHC II)
  • IFNy (R) (increases MHCII)
  • Lauric acid, (CD40, CD80, CD86). (R)

    I am wondering if you can help me out… I am experiencing severe symptoms that seem to really get worse in the first half of my menstrual cycle when Estrogen in high, and notice a remitting of symptoms in the 2nd half when Progesterone is dominant. I remember reading that Progesterone helps either TH1 or TH2 dominant people, but cannot recall? Id like to know, so that I can treat the right one. Any thoughts? I also react very badly to Echinacea. Thanks!!

      Hi Kristine, you can book an appointment with Joseph Cohen at http://selfhacked.com/contact, or with me or Dana at selfhacked.com/consult-specialists/. Looks like this not just estrogen and progesterone here.

  • pmalowe

    The link for the blood test has expired. Is there another place that has the test info?

  • Dona Mckinley

    Is decaffinated coffee (Swiss water filtered beans) ok if TH-2 dominant?

  • YimYam

    What do you recommend to be the dosage for Black cumin seed oil in mg in capsule form? I’ve read a teaspoon equates to 4000mg, does this mean you are recommending 4000-8000mg per dose?

    1. Joe

      more -14g

      1. YimYam

        According to my scales 14g in liquid form is 3 teaspoons per meal. Also from my experience there is a significant difference in how I feel when I consume 3 instead of 2.

        Can you confirm it’s ok to keep at this dose per meal?

        1. Joe

          Yup

          1. Tuomo

            And what if bitterness of the oil differs quite much? I bought one plastic bottle, bitter, and after that I bought one bigger (of glass), and it’s much easier to swallow. Maybe this new black cumin seed oil is not so effective? :/

    Joe, what about reports that luteolin reduces progesterone levels? And do the drawbacks of tocotrienols outweigh the benefits, i.e. should they be taken as a taken or not as a supplement?

    1. Joe

      Luteolin- study please?
      Tocotrienols – depends if you have a need for them.

    Rooibos seems to have a paradoxical effect on me.

    If I feel balanced and non symptomatic in the morning and drink it I feel it sets off a little stress response. But, if I eat something and it sets the stress response off, drinking rooibos helps me feel balanced again and less symptomatic.

    Can you explain this phenomenon?

  • George

    Apple’s seem to be one of the only foods I can tolerate and feel balanced and non symptomatic after.

    I definitely have issues with histamine rich foods. I have most of the symptoms of TH2 but I also have alot of symptoms from TH1, a mixture of both.

    I just need to simplify all of this already simplified info, so i understand.

    If I was TH1 dominant and experiencing symptoms and I was to take/do something which reduces TH1 or raises TH2. In theory my symptoms and “reaction” to foods would be reduced, right?

    Will you be adding lifestyle factors, foods etc at a later date?

    1. Joe

      “Will you be adding lifestyle factors, foods etc at a later date?”
      Maybe

      1. YimYam

        How long are we talking, Joe?

  • George

    Thank you, I am testing your recommendations to cure my brain fog. Hope it helps!

    Won’t leucine exacerbate the condition due to increased mTOR activity?

  • Joanna

    Does the process of decaffeinating affect the level of Theaflavins in black tea?

    1. Joe

      Prob

  • Jacki Morgan

    Thanks. Really helpful

  • vili

    Thanks for your efforts 🙂

    1. YimYam

      Do you recommend meat to be eaten on the day the packaging is opened because of the histamine load?

      I’m aware that if you buy to much you just whack it in the freezer.
