Am I able to choose a product myself or do I need to consult a doctor?

For serious health problems, it is advisable to consult an expert, who understands the effects of medicinal mushrooms. For less serious health problems or in the case of preventive use, you can choose a product yourself according to its description.


Can I combine different medicinal mushrooms?

Yes, that increases their efficiency in particular  by strengthening the immune system. However, you need to choose according to your problem’s symptoms. For example, we often combine Cordyceps in the morning and Reishi in the evening


Can I take medicinal mushrooms as a prevention?

Yes. It is a great idea to perform preventive "mushroom treatments" every year for about three months. Especially for people at risk (oncological diseases in the family or you experienced an oncological disease yourself) or weakened people (long-term stress, overworked people, chronic diseases).


How can medicinal mushrooms strengthen the immune system and at the same time reduce its response, if the response is disproportionate?

These mechanisms haven’t yet been fully described by Western science, however, we  can apparently see these effects in practice. There are a number of studies, which confirm both their stimulating and their reducing effects. Therefore, we can use them both in case of a weakened immune system and in the case of  problems such as allergies or autoimmune diseases.


Why is it appropriate to use medicinal mushrooms in conjunction with conventional treatment of tumor diseases?

Cancer is a very fast and aggressive disease. This is why Western medicine has developed relatively drastic treatment systems – chemotherapy and radiotherapy - in an attempt to eliminate cancerous growth by means of toxic substances or radioactivity, which is actually a great idea. The problem is that healthy cells are destroyed together with the cancerous cells. And this leads to an already weakened organism being weakened further (weakening Zheng Qi according to Chinese medicine). Therefore, the side effects of this treatment are fatigue, hair loss, nausea. And this is why cancers often recurs.

Using common herbs, we could alleviate these negative side effects. However, there is a risk of weakening the positive effects of chemotherapy or radiotherapy as well. And of course we don’t want that.

Therefore, it is appropriate to use medicinal mushrooms. They will support the immune system, strengthen the body for the further fight, and at the same time actively reduce multiplication or growth of cancer cells. And on the other hand, they won’t weaken the effects of chemotherapy or radiotherapy. These attributes of medicinal mushrooms have been demonstrated by many scientific studies and also in many cases of clinical practice.

Recently, there have been many articles about the harmfulness of chemotherapy. In reality, the patients aren’t destroyed by cancer, but by the weakening of their organism as a result of the drastic conventional treatment. In our opinion, the truth is somewhere in the middle.

This is why we think that synergistic use of both drastic conventional treatment and mycotherapy, which harmonizes the human organism, is important. 


Why do you report the percentage of Beta-D-Glucans?

Beta-D-Glucans are among the main active ingredients and it is for this reason that people use medicinal mushrooms. Therefore, the optimal percentage of Beta-D-Glucans is important and every good producer should indicate it for each product. 

It is important to mention that in addition to Beta-D-Glucans, mushrooms contain many other active substances. And this unique ratio is what differentiates the effects of one mushroom from the effects of another. This is why Reishi harmonizes better the psyche and Turkey Tail destroys HPV more efficiently 


How can your mushrooms be up to 50 times stronger than mushroom powder?

Mushroom powder/biomass contains 0.5 to 3% Beta-D-Glucans, depending on the mushroom. Our extracts contain 10-50% Beta-D-Glucans I.e. they are up to 50 times more concentrated than mushroom powder. The Beta-D-Glucans content is the highest in the first ten days of mushroom growth. That is why we use younger mushrooms for our production (for example in case of Reishi 6 to 9 months). If the mushroom is older, the price-performance ratio isn’t optimal - mushroom growing is cheaper, if you use older ones, because they’re heavier – you’ll have more weight for less money, but their quality will be much lower (less Beta-D-Glucans). 

If you have an extract 10:1 of old mushrooms, their quality (efficiency) may be lower than in case of an extract 5:1 from young mushrooms. So concentration in medicinal mushrooms has no information value.


How long do I have to wait for medicinal mushrooms to be effective?

This is very unique to each individual. Some patients report improvement after a few days of use. On average, significant improvements appear after two to three months of use in the case of chronic diseases. A general guideline of Chinese medicine says: "How many years the disease lasts, is how many months it takes to be cured." It is important to also try and adjust your diet and overall lifestyle (if necessary).


Do your mushrooms have any side effects?

We haven’t noticed any significant side effects in our practice nor in our colleagues' experience. Various clinical trials are still underway, but they don’t report any significant side effects with regard to medicinal mushrooms.

However, as our extracts are strong, mild digestive problems are sometimes reported in patients with weakened digestion. E.g. softer stools, flatulence and pressure around the stomach. Usually, you can decrease the dosage in the first days of use and these problems will disappear. Or eat some light food after taking the mushroom extracts.

It is recommended to take the mushrooms “on an empty stomach”. The minimum interval is 30 minutes before a meal or 60 minutes after a meal. This means that you don’t have to eat mushrooms strictly before breakfast, but perhaps an hour after it.


What is the difference in the effectiveness between raw powder/biomass from mushrooms and an extract?

Ozaida products are made of extracts from medicinal mushrooms. Our suppliers use special hot water extraction procedures to preserve the full spectrum of the active ingredients found in  a raw mushroom. 

There are two benefits of the extract - the active substances’ bioavailability and their higher concentration in the final product. The advantage of the mushroom raw powder is that it maintains the proportion of all substances. On the other hand, people don’t use medicinal mushrooms for the vitamins, but more so because of the polysaccharides (especially beta-d-glucans). The cell wall of the mushroom, which contains the active substances, is composed of chitin. And  as humans don’t have the necessary enzymes for digesting chitin, they can’t release the active substances from the cell wall of the mushroom  during digestion and their organism discharges them.

Extraction using hot water can break the chitin barrier and extract the maximum amount of the effective substances from the mushroom. Thanks to extraction, the proportion of active substances increases up to 50 times.
The disadvantage of extracts is their higher price compared with mushroom powder, since much more biomass is consumed during their production. Still, we manage to keep Ozaida medicinal mushrooms at a very affordable price level.


How long can I use your medicinal mushrooms?

This is very specific to each individual. Mushrooms can be used for a long time.

However, using mushrooms for some health problem for a year without anything changing makes no sense. This is a good strategy for some sellers. We think some effect should be seen within 2-3 months at most. If we see progress, then we can use the mushroom for a year or even longer. For oncological diseases, we recommend using medicinal mushrooms for the duration of conventional treatment (chemotherapy, radiotherapy, biological treatment and surgery) and then for about 2 months after it ended. In the last month of use, we continue to reduce the dosage until it reaches zero. After being cured, you should use preventive mushroom treatment every year for about 3 months.

It’s also advisable to use the 5 day use rule, 2 days of pause for most health problems. In case of long-term use we recommend that you always take a seven-day break after three months.


Are your mushroom extracts safe?

Yes. All batches of Ozaida medicinal mushrooms are controlled by an independent Canadian laboratory. Tests are carried out on about 500 harmful substances - pesticides, heavy metals and micro-organisms. We test all the mushrooms’ raw ingredients, so that they contain only high-quality mushroom polysaccharides.


Can I use such remedies during chemotherapy?

Unlike traditional Chinese herbal medicinal products (which usually improve the side effects of chemotherapy but at the same time weaken its aggressive effect on the destruction of cancer cells), medicinal mushrooms are very suitable for use during chemotherapy. It is advisable to start taking medicinal mushrooms before starting chemotherapy. Many clinical trials have already been performed, as well as  studies, which have demonstrated the synergistic effect of chemotherapy and medicinal mushrooms. They both alleviate the side effects of chemotherapy and intensify the overall treatment effect. The same applies to radiotherapy. We recommend consulting your attending physician about the use of medicinal mushrooms during chemotherapy or radiotherapy.


How do I find out about the dosage for my problem?

Observe the recommended daily dose for each mushroom. If you take medicinal mushrooms for any particular health problem, it’s best to consult with a doctor or a Chinese medicine practitioner.


Can I overdose with medicinal mushrooms?

It is unlikely. Nevertheless, observe the recommended dosage. Arbitrarily increasing the dose is not effective, as the body won’t absorb more of the active substance and it is then excreted from the body. According to our experience, it makes no sense to use more than 5 grams of extracts per day.


Are medicinal mushrooms suitable for children?

Yes, but it is necessary to administer doses proportionately to their age. For example, children between the ages of seven and ten should only use half the recommended daily dose.


Can extraction damage active substances?

On the contrary. Active substances such as beta-d-glucans and  other bioactive substances are contained in the cell walls of the mushroom, which are protected by chitin. Humans have no enzymes to digest chitin. Gentle extraction with hot water must be carried out in order to achieve extraction of all bioactive substances. Tests are carried out on all batches of Ozaida products with regard to the amount of beta-d-glucans contained in the extract and this amount is indicated on each product.

What is the "double extraction", which you describe in the case of some products?

It is a common procedure of processing some medicinal mushrooms. First, extraction is done with hot water and  because some substances are not water-soluble (e.g. triterpenes) in Reishi, a second "extraction" is performed with alcohol, the so-called condensation with alcohol.


Are there any interactions between medicinal mushrooms and drugs or other dietary supplements?

We are not aware of any negative interactions between medicinal mushrooms and drugs or other dietary supplements. However, it is generally appropriate to observe the principle of taking the mushrooms “on an empty stomach” even with regard to drugs/other dietary supplements.

Only Auricularia mushroom should not be taken together with  blood thinning medicines (e.g. with  Warfarin).


If medicinal mushrooms begin to reduce my hypertension, can I drop the medications prescribed by my doctor?

No. Medication can only be discontinued with the consent of the doctor who prescribed them to you.


Can Ozaida medicinal mushrooms contain heavy metals or radioactivity?

No. Due to stringent cultivation conditions, Ozaida products cannot contain heavy metals or any other unsuitable substances. Some manufacturers expose mushrooms to radiation to destroy micro-organisms. However, Ozaida medicinal mushrooms are not exposed to radioactive radiation in any production phase. Tests are performed on each batch in an independent Canadian laboratory.
