Limb Bagging - How to Target Troublesome Skin Issues

Ozone Therapy Made Easy

Many people reading this blog are already familiar with the benefits of ozone therapy and all the science which backs up this discipline.

Bag it up!

A lesser known ozone therapy technique is limb bagging. Limb bagging is a home ozone therapy protocol designed to provide localised benefit, where the entire limb is enclosed inside an ozone resistant polythene bag which is then filled with medical ozone. When a wound or infection is smaller than around 30mm, we recommend the use of ozone cupping but for larger areas, a limb bag is the ideal choice


For stubborn complaints

This method has been found to be especially effective in treating poorly-healing wounds, abrasions, skin infections, herpes, decubitus ulcers, cysts, fungal skin infections, burns and radiodermatitis.

How to video

This video outlines the conditions that limb bagging can support, the equipment needed to administer limb bagging and how to perform this safely and effectively at home.

Following the science

This literature review conducted by Griffith University in Australia assessed nine placebo controlled trials of topical ozone therapy for wound healing. This included various types of wounds such as venous and arterial ulcers), gunshot wounds, and chronic burns. 

The authors made the following conclusion: 

"Primary outcomes Meta-analysis of the 9 studies (n = 453 patients) revealed a significant (P < .05) improvement in wound closure (wound healing and percent wound closure) with ozone therapy compared with the control. All studies demonstrated improvements in primary outcomes with ozone therapy. The difference in outcome favouring ozone therapy over standard care was very high..."

Better than standard care

 Another 2022 study of patients suffering from venous ulcers in Spain compared the standard hospital treatment with ozone limb bagging. They found the following results:

"Both the groups showed an improvement in s.o.'s condition, but the velocity of improvement was more rapid in the second group (30 days in the first group, 15 days in the group treated with local ozone therapy)."

Ozone has been proven effective against difficult to treat infections such as antibiotic resistant MSRA.

Video Transcript


Welcome to the Natural Ozone YouTube Channel. My name is Kim Saxton, director of Natural Ozone, a family run Kiwi company dedicated to helping you harness the many benefits of ozone.

Please note, this video is not intended as personal medical advice. For all medical issues, please consult your health professional. Ozone therapy does have a firm scientific basis, in fact there are over 11 000 scientific articles related to ozone therapy on the Pub Med data base in the USA. 

In this video, we will discuss how to perform limb bagging

Why perform limb bagging?

Limb bagging is used to apply ozone to a foot, leg, hand or arm.

What conditions does limb bagging support? 

Please note: Natural Ozone do not claim that this protocol will cure any conditions. There is a wealth of scientific data which you can access through the Natural Ozone study library to help guide your decision making. We always recommend that you follow the advice of your chosen health practitioner.

Limb bagging concentrates the ozone onto the skin of the area being treated.

Ozone has been used for over 100 years to support people with a range of skin problems such as MRSA, ulcers and other types of issues such as rashes, infections and other chronic skin conditions. Ozone is very well documented and proven to be highly effective against most viruses and bacteria. Because it attacks the pathogen directly by oxidising the protective layer, it can be effective against antibiotic resistant pathogens.

Home ozone therapy equipment needed to perform limb bagging 

To perform limb bagging you will need the following equipment

  • Natural Ozone Home Ozone Therapy Protocol Handbook
Ozone treatment protocols
 Oxygen bottles

  • Small fan or activated carbon mask
These items are available in our ozone therapy bundles. 


How to perform limb bagging at home using medical home ozone therapy equipment 

Connect the oxygen supply to the O2 in nozzle at the back of your Ozonode. We have separate videos on setting this up depending on whether you are using an oxygen concentrator or bottled oxygen. So, if this is the first time you are using your home ozone therapy equipment, please visit the appropriate video.


You will see that your Ozonode has a three-position switch marked M1, off, and M2. When we use the settings one to four, we have the switch on M1 and use the outlet marked O3 out 1

When we use the settings five or six, we turn the switch to M2 and the outlet marked O3 out 2.

Ensure that the ozonode is plugged in and switched on at the wall. Set the power switch to M1

Which level setting you will use depends on the concentration of ozone that you intend using.

This is measured in micrograms per litre, also called gamma.

Refer to the chart on your machine to determine which level and flow rate correspond with the gamma you require.

Please consult your health practitioner for personal medical advice. In the protocol handbook, we pass on the general advice from the Madrid Declaration on Ozone Therapy from the International Scientific Committee of Ozone Therapy.

It is always advised to start low and slowly build up the dosage over a long period of time.

In this case, we are going to make medical ozone at 22 gamma with a flow rate of 1/4 litre/minute. Referring to the chart, we can see that we need the setting L3.

If you are using an oxygen concentrator, allow 5 minutes for it to warm up, then turn the knob on the low flow meter until the ball is hovering around 1/4

If you are using a gas bottle, turn on the tap and then adjust the low flow regulator to 1/4

Ozone gas is a lung irritant, so you don’t want to breathe in too much (although a small amount is considered safe.)

Given that it is possible that a small amount of ozone can leak out of the bag, you use a second hose to bring excess ozone to the ozone destruct function on the Ozonode

Use a warm wet flannel to moisten the area that you are planning to treat. Some people prefer to use a humidifier when conducting this protocol. For more information on this, please see our video “Home Ozone Therapy Protocols – How to Use a Humidifier” 

Place the limb bag over the area you wish to treat and insert the two silicon tubes. Attach one tube to the nozzle marked O3 out 1 and attach the other to the nozzle marked Ozone Destruct

Using a Velcro strap or rubber band, seal the bag as best you can, ensuring to expel all the air.

Press the button L3

Relax for the duration of the treatment, which can be from 5 to 20 minutes. Please consult your health professional for personal advice regarding the treatment regime.

We recommend that you use either an activated carbon mask or else point a small fan towards your face during the insufflation and while removing the bag after the treatment

Remember to switch off the machines and turn off your oxygen supply.

Wash, dry and sterilise the limb bag before storage.
