The TCM community is mourning the loss of Giovanni Maciocia, a man who dedicated his life to sharing his knowledge and passion for Traditional Chinese Medicine with today’s practitioners.
His textbook, Foundations Of Chinese Medicine, was one of the first books I bought when I started school and I still use it for reference today.
His passing has left a void in our profession, but his countless textbooks, courses, webinars and newsletters contain a vast amount of information that will continue his legacy.

Spent the day in Niagara-on-the-Lake at the Neob Lavender Festival learning all about the many uses of lavender from essential oils, to perfumes, to soaps, insect repellents and even in cooking.
In aromatherapy, lavender oil has long been used for it’s relaxing and calming effect on the nervous system. It helps to relieve stress and anxiety and promote sleep.
Can’t wait to try out all the lavender infused goodies I bought at the festival! 💜
“Nothing is more soft or more flexible than water. Yet nothing can resist it.” -Lao Zhu
THE WATER ELEMENT 💧🌊
Water is the most yin of all the five elements. The organ systems associated with Water are the Kidneys and Urinary Bladder, which rule water metabolism and maintain homeostasis, a dynamic continual rebalancing.
As we age we lose water, and our bodies begin to dry out. Our bones and hair become more brittle, our skin loses its elasticity, our minds may lose their accustomed flexibility. While acknowledging these changes, Traditional Chinese Medicine gives us numerous mental, physical, and nutritional tools to help slow the progression of the apparently inevitable by offering ways to augment the water reserves within us.
Turns out the “stress” from labour is beneficial for the baby because it helps with lung maturation, improved sense of smell (important for breastfeeding), decreased obesity and higher cognitive function. Contractions are good for the baby!
You know the drill when it comes to hormonal blood work; it’s a lot of poking and prodding on multiple days of your menstrual cycle. In my experience, my patients have had all the right testing done (mostly), but no one has taken the time to sit down with them and explain what the results truly mean.
The biggest pitfall of serum (blood) hormone testing is that the reference ranges are MASSIVE. Which means it is highly unlikely that your results will be deemed “abnormal” even though you know something is wrong. So that’s what this blog is for; I’m going to break it all down for you and discuss what the results mean and the REAL range you’re looking for. Note: the following reference ranges are for women and are Canadian units.
What it is: Estradiol, along with LH and FSH, stimulate follicle (egg) maturation. It’s also responsible for female sex characteristics, thickening of the endometrial lining, and bone protection. Estrogen can also be converted from fat, in both males and females, by an enzyme called aromatase.
What it means: Low estradiol is present in peri-menopause and menopause. Elevated estrogen is present in early premature ovarian insufficiency (followed by low levels), and in estrogen dominant conditions like: PMS, endometriosis, PCOS, and obesity.
Follicular 77-921 pmol/L
Luteal 77-1145 pmol/L
The “real” range: The width of the above ranges is ridiculous! Estradiol should be tested on day 3 and should be lower than 200 pmol/L and higher than 80 pmol/L. A level higher than this is a sign that the body is trying too hard to stimulate egg development, and the ovaries are not responding. In this case, you will likely see elevated FSH too.
2) FSH (follicle-stimulating hormone)
What it is: The name says it all. FSH is in charge of the development and maturation of follicles.
What it means: High levels are diagnostic of menopause, ranging from 27-133 IU/L. When your body is pumping out more FSH than normal, it’s a sign that the ovaries are not responding (just like estrogen). Low levels of FSH are typically present in PCOS.
Follicular 3-8 IU/L
Mid-cycle 3-22 IU/L
Luteal 1.5-5.5 IU/L
The “real” range: Higher than 8 IU/L on day 3 (that’s the 3rd day of your period) is too high and the value is only going up from there. 6 IU/L is as good as it gets on day 3.
3) LH (Luteinizing hormone)
What it is: Ah, the hormone everyone knows and loves! The LH surge triggers ovulation and is measured by urine strips. LH also contributes to the maturation of eggs. You may not know that estrogen surges right before LH, which can also be used to detect ovulation.
What it means: On day 3, an LH to FSH ratio greater than 2:1 is indicative of PCOS. LH is elevated in PCOS for so many reasons I’ll need to dedicate another blog to it. Elevated LH also stimulates elevated testosterone production, and in turn estrogen production. Contrary to what you may think, high LH actually inhibits ovulation instead of stimulating it.
Follicular 2-12 IU/L
Mid-cycle 8-90 IU/L
Luteal 1-14 IU/L
The “real” range: LH should be almost equivalent to FSH on day 3. 6-8 IU/L is ideal.
What it is: Most of the body’s progesterone is produced by the outer coating of the egg, called the corpus luteum. After you ovulate, progesterone levels increase to maintain the endometrial lining and prepare for embryo implantation. Progesterone also stimulates the production of a thick mucous that covers the cervix so no sperm can enter the uterus (FYI this is the basis of hormonal birth control).
What it means: A low level of mid-luteal progesterone indicates anovulation and luteal phase defect (short luteal phase) and predicts implantation failure/ early miscarriage.
Luteal 4-50 nmol/L
The “real” range: On day 21 the minimum value is 10 nmol/L to have ovulated and 20 nmol/L to carry a pregnancy. Day 21 is arbitrary if you don’t ovulate on day 14. Progesterone is best-tested 7 days after you ovulate.
What it is: The main function of prolactin is to stimulate breast milk production. However, elevation can also occur due to the following: benign pituitary tumor, periods of high stress, hypothyroidism, PCOS, and certain medications.
What it means: Elevated prolactin inhibits the release of GnRH, which then inhibits the release of LH and FSH. Without LH and FSH, follicles will not develop.
The “real” range: Prolactin levels as high as 50 ug/L can inhibit ovulation, but small increases by a few points are relatively harmless. One-time elevation should be followed by repeat testing. As mentioned, stress is a major influence on this hormone.
What it is: A precursor hormone to both estrogen and testosterone.
What it means: DHEA is often evaluated in PCOS, as elevations in this hormone increase androgen levels. It may be prescribed to improve ovarian reserve (but not without fun side-effects).
Reference Range: <9.8 umol/L
What it is: Produced from DHEA, this hormone is the precursor to testosterone.
What it means: Elevated androstenedione is found in PCOS and adrenal hyperplasia. Both conditions inhibit ovulation. It may be elevated in isolation, or with testosterone.
Follicular 1.2-8.7 nmol/L
Luteal 1.1-8.2 nmol/L
What it is: You know this hormone for its role as the primary male sex hormone, but it’s important for women too! In the ovaries, testosterone is produced by the stromal cells and converted to estrogen. It participates in follicle growth and development, not to mention male and female libido.
What it means: Too much is present in PCOS which is far from ideal, but too little can inhibit ovulation and egg development.
Total testosterone 0.3- 1.8 nmol/L (some labs up to 4 nmol/L)
The “real” range: Testosterone is extremely tricky to test accurately. Free testosterone is a better measurement than total and the reference ranges (depending on the lab) have huge variability. In order to test free testosterone you need to test total testosterone and sex hormone binding globulin.
9) AMH (Anti-Mullerian Hormone)
What it is: It’s a hormone that can depict the female egg reserve because it is secreted by the eggs in the ovaries. The more eggs you have, the higher the value will be. Not surprisingly, AMH decreases with age. This is the only hormone test we have for predicting ovarian reserve.
What it means: A lower value for your age means you have a lower number of eggs than the average female. A much higher value for your age is indicative of PCOS, as the cystic ovaries in PCOS secrete excess AMH.
Reference Range: The numbers are averages based on age:
< 33 = 2.1 ng/mL
33-37 = 1.7 ng/mL
38-40 = 1.1 ng/mL
> 41 = 0.5 ng/mL
The “real” range: At any age, a value > 3.15 – 4.45 ng/mL warrants further testing for PCOS. A value of 6.8-10 ng/mL is diagnostic.
10) TSH (thyroid stimulating hormone) & Antibodies (anti-TPO, anti-TG, anti-TSH)
What it is: TSH is released by the anterior pituitary, which then stimulates the release of thyroid hormones (T3, T4) from the thyroid gland. TSH above the reference range with symptoms present is diagnostic of hypothyroidism, and below is hyperthyroidism. TPO and TG antibodies cause the thyroid condition known as Hashimoto’s, anti-TSH is more commonly present in Graves’.
What it means: Deficient thyroid function affects egg quality, embryo quality, and implantation rates. Combine that with thyroid antibodies, and there’s an increased risk of miscarriage.
TSH 0.32-4.0 mIU/L
Antibodies should all be negative
The “real” range: TSH should be < 2.5 to prevent miscarriage. A full thyroid lab panel (with individual thyroid hormones) is certainly necessary in cases of recurrent miscarriage.
