Turmeric Herb Benefits and Uses



Most people are familiar with turmeric (scientific name: Curcuma longa1) as a yellow spice that’s used in Indian cuisine, and has a peppery, warm and bitter flavor.2 Traditionally called “Indian saffron,” turmeric comes from a rhizome with rough brown skin, dull orange flesh3 and an earthy scent said to be more pungent than ginger.4 However, there’s more to this vibrant spice than meets the eye.

Through the years, studies have been extensively conducted on the potential health benefits of turmeric, and the results were consistently positive. As a result, turmeric was given its well-deserved nickname: the “Spice of Life.”5 There are many ways you can incorporate this spice into your daily life. Learn more about turmeric and its benefits, and how they can help improve your health and well-being.

Turmeric’s Health Benefits

The health benefits turmeric offers can be attributed to curcumin, a well-studied bioactive compound that may:

Help maintain a healthy digestive system by facilitating proper digestion6

Modulate some of your genes7

Positively control various physiological pathways8

Make your cells’ membranes more orderly9

Affect signaling molecules, because curcumin can directly interact with inflammatory molecules, cell survival proteins, DNA and RHA, carrier proteins and metal ions10

As mentioned earlier, turmeric is known as the “Spice of Life,” and curcumin has a role to play in making this spice earn this moniker. Curcumin was proven by studies to help combat diseases such as:

Parkinson’s and Alzheimer’s disease — Curcumin is a known antioxidant, anti-inflammatory and neuroprotective agent, and is said to promote lipophilic action and improved cognitive function, potentially helping people with these conditions.11,12

Osteoarthritis — A 2016 animal study showed that curcumin may help slow down the rate of osteoarthritis progression and address related pain.13 Another study from the same year also revealed that curcumin assisted in improving quality of life and addressing pain and other osteoarthritis symptoms, by improving your body’s physiological pathways.14

Cancer — Numerous studies have been conducted regarding curcumin’s potential anticancer capabilities.15,16,17 According to Dr. William LaValley, whose clinical work mostly focuses on the treatment of cancer, curcumin appears to be useful for just about every type of cancer, because it can affect multiple molecular targets via many pathways. Curcumin is also nontoxic, and does not target healthy cells — instead, it selectively targets cancer cells.

The antibacterial properties of curcumin are nothing short of extraordinary as well, as it may be effective against gastritis, peptic ulcer and gastric cancer, which are all caused by Helicobacter pylori (H.pylori) bacteria.

This was proven in a 2009 study, wherein curcumin effectively inhibited the growth of H. pylori in vitro in mice, regardless of the genetic makeup of the bacteria strains.18 H. pylori is a group 1 carcinogen19 that affects more than half the global population.20 Some of the other health benefits linked to curcumin include:

Supporting healthy cholesterol levels21

Enhancing wound healing22

Preventing low-density lipoprotein oxidation23

Protecting against cataracts,24,25 liver damage,26 pulmonary toxicity and fibrosis,27 and radiation-induced damage28

Reducing symptoms of rheumatoid arthritis29 and multiple sclerosis30

Lowering risk for thrombosis,31 myocardial infarction32 and possibly Type 2 diabetes33

Turmeric’s Many Uses

Turmeric has a long history of medicinal use for Ayurvedic medicine and traditional Chinese medicine (TCM). Evidence showed that turmeric may help alleviate wounds, sprains and swelling, liver disorders, skin diseases and respiratory or gastrointestinal problems.34 Aside from being a common ingredient in Indian dishes, turmeric is used for making mustard. In fact, the distinct yellow color of this condiment comes from this spice.35

Turmeric also works as a dye for textiles and other articles of clothing.36 It’s said that Hindu and Buddhist monks who traveled all over the world used this spice to dye their robes.37 During early times, the children from Kerala, a state in southwest India, were given turmeric-dyed clothing to wear during the Onam Festival because the spice’s color was said to be associated with Lord Krishna, a prominent figure in Hinduism.38

In a traditional Hindu wedding ceremony, the groom ties a turmeric paste-dyed string called a mangala sutra around the bride’s neck, signifying that the woman is married and can run a household. Most Hindu weddings today still continue this tradition, and it’s considered the equivalent of exchanging wedding rings. People living in some parts of Southern India also still wear a piece of the turmeric rhizome as an amulet to protect themselves from evil spirits.39

Growing Turmeric at Home

You can grow turmeric in your backyard or in indoor containers from rhizomes or root cuttings, but not from seeds. To grow turmeric, you need high-quality soil or growing material with high amounts of organic material-like manure, and a turmeric rhizome.

The plant will benefit from good-quality organic fertilizer or compost, especially when administered during growth of turmeric shoots. Just make sure that when you apply the fertilizer, it does not directly touch the plant. The fertilizer’s nutrients should reach the soil, but without touching the stems. Follow this simple step-by-step method if you want to grow turmeric:40,41

How to Grow Turmeric


1. Cut rhizomes into smaller sections with two or three buds each.

2. Fill 3-inch pots or containers with good-quality potting soil.

3. Place rhizome flat onto the soil, and cover with more potting soil.

4. Water the plant and place the pots or containers into clear plastic bags.

5. Move the pots or containers to a warm location of around 86 to 95 degrees F. Take note that colder temperatures may cause the turmeric to grow very slowly and possibly rot.

6. Once the turmeric rhizome is planted, avoid watering until you notice shoots rising out from the soil.

Edible turmeric rhizomes take around eight to 10 months to mature. Once rhizomes are fully grown, you can harvest them. Ideally, matured roots should be harvested all at once. You’ll know the turmeric is ready to harvest if the plant’s flowers fade and the leaves turn yellow. Home Guides SF Gate demonstrates how to harvest fresh turmeric:42

” … [C]ut off the tops of the plants with shears to make harvesting easier — this isn’t required, but it allows you to get to the underground rhizomes without having to dodge the large leaves. Water the area thoroughly to soften the ground, then dig up the rhizomes using a trowel. Each plant should have a small handful of rhizomes …”

If you want to grow turmeric the following season, save a few rhizomes for planting.43 Turmeric is best planted in tropical areas where it may receive high amounts of warmth and moisture,44,45 particularly in USDA zones 8 to 11. When you should be planting turmeric depends on your area. Good Housekeeping notes that in most parts of the U.S., turmeric will flourish if you plant it indoors, although if you live in Zones 8 to 11, you can plant turmeric outdoors for the entire period.46

If you live in areas with cooler climates, plant turmeric indoors and then move it outside once the threat of frost is gone. This reduces the risk of the plant becoming dormant.47 After moving the plant outside to a warm area, keep the soil wet and moist, and provide partial shade to protect leaves from sunburn.48

Cooking With Turmeric

Want to add turmeric into some of your dishes? Take your pick from either fresh or dried turmeric. Fresh turmeric rhizomes look like gingers. The Kitchn notes that you can find fresh turmeric root in your grocery’s produce section, as well as in health stores and Asian or Indian grocery stores. Pick firm roots and avoid soft, dried or shriveled pieces.

Fresh turmeric, depending on the root’s maturity or tenderness, can be peeled before chopping, cubing, grating or even juicing it. If you won’t be using turmeric immediately, store them properly. Place turmeric in a glass jar or storage dish or other airtight container for at least a week, or freeze for several months.

Dried turmeric is usually sold ground or whole, and is made by peeling, boiling and drying rhizomes. Buy them from ethnic and specialty shops, which usually have fresher stock and a faster turnover time compared to grocery stores.

When buying dried turmeric, make sure to smell it, as aroma is a good indicator of freshness. Keep it in an airtight container and store in a cool and dark place for up to a year. While it has the flavor and color the spice is known for, one major caveat is that the drying process reduces its pungency and the quantity of essential oils in the spice.49

You can use fresh or dried turmeric for rubs or marinades, just like in these Satay Chicken Skewers and Turmeric Cauliflower recipes. You can also chop fresh turmeric and add it into a salad, similar to what I did with my lunch recipe. Turmeric can be even made into healthy beverages, such as this ginger and turmeric latte, which combines the earthy flavors of these related root herbs:

Ginger Turmeric Latte Recipe


1 teaspoon fresh, grated turmeric or dried turmeric spice

1 teaspoon grated ginger

1 tablespoon coconut sugar

2 teaspoons coconut oil

Pinch of sea salt

1 cup of almond milk


1. Combine the grated turmeric and ginger, coconut sugar, coconut oil and sea salt in a blender.

2. In a small saucepan, heat the almond milk over medium heat until it’s just simmering.

3. Pour the hot almond milk into the blender and whirl until smooth and frothy.

Try Turmeric Essential Oil, Too

Research has shown that turmeric essential oil exhibits anti-inflammatory,50 antimicrobial,51 antifungal52 and antiseptic properties.53 To make this oil, the turmeric plant’s roots can be steam-distilled or powdered until fluid is extracted from the substance.54 Some of the chemical compounds in this oil include:55

  • Turmerone
  • Ar-turmerone
  • Turmerol
  • Limonene
  • Cineole
  • Curcumene
  • Zingiberene
  • Bisabolene
  • Beta-phellandrene

Turmeric oil may be help alleviate arthritis.56,57 However, if you plan on using this essential oil topically, I advise you to take a skin patch test first to check for allergic reactions and talk to your doctor to determine whether this oil is appropriate for you.

Can Turmeric Cause Side Effects?

Consuming excessive amounts of turmeric can predispose you to some side effects. For instance, turmeric may cause nausea, upset stomach, dizziness or diarrhea. It also may interact with:58,59

Anticoagulant or antiplatelet drugs like warfarin (Coumadin), clopidogrel (Plavix) and aspirin and raise bleeding risk

Stomach acid-reducing drugs such as cimetidine (Tagament), famotidine (Pepcid), ranitidine (Zantac), esomeprazole (Nexium), omeprazole and lansoprazole (Prevacid) and lead to increased stomach acid production

The following groups of people must avoid taking turmeric or related products because they have a high risk for side effects:60

Pregnant and breastfeeding women — High amounts of turmeric may trigger a period or stimulate the uterus, resulting in health risks for a pregnancy. There is also very little research about turmeric’s possible effects on breastfeeding women.

People with gallbladder problems such as gallstones or a bile duct obstruction — Turmeric can worsen these conditions.

People with bleeding problems or disorders — Turmeric may slow down blood clotting and increase both bruising and bleeding risk.

People with gastroesophageal reflux disease (GERD) — Turmeric may worsen stomach problems in GERD patients.

Diabetes patients — Reduced blood sugar levels may be caused by curcumin abundant in this spice.

Iron deficiency — Consuming high amounts of turmeric may negatively affect the body’s iron absorption.

People with hormone-sensitive conditions like breast, uterine or ovarian cancer, endometriosis, or uterine fibroids — WebMD reports that the curcumin in turmeric possibly could act similarly to the estrogen hormone, and  exacerbate some hormone-sensitive conditions.

However, with certain hormone-sensitive cancers, there are studies showing that turmeric can decrease estrogen’s effects in those cancer cells and may be beneficial for people diagnosed with hormone-sensitive breast cancer.61,62,63 Err on the side of caution and reduce turmeric consumption if you have been diagnosed with hormone-sensitive conditions.


Men who consume turmeric excessively may be prone to reduced testosterone levels and lessened sperm movement. If you’re scheduled to undergo surgery, reduce or avoid turmeric consumption, as it can slow down the blood clotting process and trigger excessive bleeding during and after the procedure.64

Ford government to resume arbitration hearings with OMA




The Ford government will resume binding arbitration hearings with the association representing the province’s physicians, according to a memo the group’s head sent to members Friday afternoon.

In her letter, Dr. Nadia Alam said the Ontario Medical Association (OMA) received formal notice Friday morning that “the government has agreed to resume arbitration hearings on our Physician Services Agreement.”

The hearings, which were originally scheduled for Saturday, are now rescheduled for Tuesday to Friday, Alam said.

“It is the OMA’s sincere hope this is the start of a more effective working relationship between the OMA and the Government of Ontario, in order to fix the crisis in our health care system,” she added. 

“We both want to serve the health-care interests of our patients, the people of Ontario.”

The provincial government informed the OMA on Monday that it had decided to pull out of binding arbitration with the association citing a “lack of confidence.”

In a letter obtained by CBC Toronto, lawyers representing the OMA called the move “unprecedented [and] an affront to the rule of law.”

No one knew retired firefighter ‘Captain Bob’ was struggling with PTSD. Now his peers are learning the signs




Bob Taylor was popular at the Richmond Fire Rescue. To many, even off the job, he was known simply as ‘Captain Bob.’

“He was always larger than life. He’d come in, ‘Hey boys’ You know, [he was] there for a good time,” said Jim Dickson, a firefighter who worked with Taylor for several years.

“Outwardly, you would never know he was struggling with any sort of mental health issue — mind you we weren’t looking either. It was not something you would talk about,” said Dickson.

In mid-October, about a decade after retiring from the department, Taylor took his own life. The cause of suicides are rarely simple, but according to a family member, Taylor had been struggling with post traumatic stress disorder (PTSD).

With his death front-of-mind, other retired members of the department are now getting some valuable PTSD awareness training.

If ‘Captain Bob’ were an active firefighter in Richmond today, he would have had access to two days of training, organized by the union along with the department. He would have joined his crew in getting training on mental health awareness and resiliency.

But his career spanned a different era. According to Dickson, who serves as treasurer for the International Association of Fire Fighters (IAFF) Local 1286 and helps run PTSD awareness training, there used to be a different strategy for coping with traumatic calls.

“If you were lucky, you were relieved from duty, which then meant, ‘Hey free night to go hit the pub,'” he said. “It would be alcohol use, typically, some black humour.

Jim Dickson, Richmond firefighter and treasurer for IAFF Local 1286, says a major shift has taken place in recent years in how firefighters understand — and deal with — traumas associated with the job. (Rafferty Baker/CBC)

“The last thing you were going to do was admit that that was still bothering you. You just put that down where all the other feelings went to die, and then you find that 30 years later perhaps that comes up.”

The culture has changed. According to Dickson, that change is as recent as the last five years. 

In an effort to reach retired members of the department, Dickson is organizing sessions at the union hall.

On Thursday, Dickson was preparing for as many as 30 retired firefighters he expected to fill the room.

Dickson said there was no way he could get retired folks in for two days of PTSD training, mirroring what active members get, so he has condensed the material into a couple of hours. And he’s thrilled with the level of interest the session has been getting.

“It really shows the willingness to embrace this idea that we are human, and that sometimes we need help,” he said.

A transplanted pig’s heart lives for months in a baboon — is a human trial next?




Xenotransplantation — the use of organs from other animals for human transplantation — may be much closer after European researchers showed they were able to transplant a pig’s heart into a baboon, and keep it alive for more than six months.

“This is huge,” said Dr. Shaf Keshavjee, the surgeon-in-chief at Toronto’s University Health Network, director of the lung transplant program, and a professor of thoracic surgery at the University of Toronto. 

Organ transplants are a life-saving miracle of modern medicine, but one of the barriers that keeps human to human transplants from being used more widely is the shortage of donor organs. That’s why for decades scientists have studied the potential of xenotransplantation. 

But over decades of experimentation in animals, researchers have encountered severe roadblocks. Keeping organs alive during transplantation proved difficult. Immune system tissue rejection has been a huge issue. And new troublesome incompatibilities between donor and recipient kept popping up.

That’s why this new success is so exciting.  “It’s one thing to have an organ transplanted that’s a xeno organ and not [being] rejected,” said Keshavjee. “But this was also working, like sustaining life.”

Surgeon Dr. Bruno Reichart from the Ludwig Maximilian University of Munich and his colleagues published their findings in the journal Nature. They refined their process over three successive groups of transplant subjects. 

“Basically you’ve optimized the organ in the pig. You’ve optimized the organ outside the body. And you’ve optimized the environment for the organ after the transplant for success,” said Keshavjee. “And that’s the Holy Grail.”

Making pigs more human-like

For decades, pigs have been the primary focus of xenotransplantation research because they are similar in size to humans and it’s more socially acceptable to use their organs than it would be to use primate organs.

The first thing the team had to do was make the pig heart more primate-like to prevent the baboon’s immune system from attacking it  something they did by genetically modifying the pig embryos.

So basically you’ve optimized the organ in the pig. You’ve optimized the organ outside the body. And you’ve optimized the environment for the organ after the transplant for success. And that’s the holy grail.– Dr. Shaf Keshajee, University Health Network and University of Toronto

“They knocked out or removed a protein that is expressed on pig cells that primates don’t have and would recognize immediately. They humanized the cells and made it so that they would down regulate the immune system,” said Keshavjee.

Protecting the heart before transplantation

Typically human hearts meant for transplantation are put on ice, flown to the recipient, and then transplanted. That didn’t work for the pig hearts that were destined for the baboons. Three baboons died of heart failure almost immediately because pig hearts proved more vulnerable to damage than human hearts.

The European team built a state-of-the-art support system, which Keshavjee likened to a “little mini-intensive care unit for the organ” to keep the hearts running while outside the body. 

They reduced the organ’s temperature from 37 degrees Celsius to eight degrees, which was optimal for preserving the organ while maintaining vital cell processes in the heart. They also provided oxygen, nutrients and hormones.  “Basically you’re repairing and keeping it sustaining it in a vulnerable time of the journey of that organ,” said Keshavjee.

Stop the pig heart from growing too big

The final hurdle for the research team was to stop the pig’s heart from growing once it was placed in the baboon’s chest.

“The issue is that a pig is designed to grow to a larger size than those small baboons,” said Keshavjee. “And so they used further molecular engineering and drugs to prevent that unwanted growth.”

All of these things are coming together now where you can see that this is going to be possible.– Dr. Shaf Keshajee, University Health Network and University of Toronto

Two baboons with pig hearts remained healthy for 90 days, which is the benchmark set by the International Society for Heart and Lung Transplant to indicate it might be ready for human trials.  They were then euthanized. Two other baboons continued to live for 195 and 182 days. 

It will still be a few years before researchers will be ready for human xenotransplants.

“I mean just to be able to say it’s gonna be a few more years is dramatically different than what most people, including myself, would have said ten years ago,” said Keshavjee. “All of these things are coming together now where you can see that this is going to be possible.”
