What causes blood blisters
Blood blisters - causes, therapy and home remedies
Formation and supply of blood blisters
Blood blisters are caused by excessive friction or mechanical pressure. For example, through tight shoes or unusual work with a tool. Due to the friction, layers of skin lying on top of one another are detached from one another and the resulting cavity is filled with tissue fluid ("normal" bladder) or with blood. Smaller blood blisters can be treated with home remedies, but a doctor should be consulted for larger ones.
Prick blood blisters? What to watch out for
Blisters in general, but also blood blisters, encourage pricking open. If they are small, this can be done at home with the necessary care. Larger blood blisters, however, belong in the hands of a doctor, as the risk of infection is too great here.
The needle used to open the blood bladder must be sterile. After piercing, the blood should be able to drain completely. Then the wound is cleaned. Calendula essence is used for this - one to two teaspoons of it are mixed with a quarter liter of boiled, cooled water and the wound is rinsed with it. A compress soaked in this can also be applied for about 15 minutes. The calendula essence not only disinfects very well, but also contributes to healing.
After the blood bladder has been punctured, the wound must always be kept clean. Repeated washing or dabbing with the diluted Calendula Essence is recommended. A ribwort tincture diluted with boiled water is also helpful.
The wound is best protected by a bandage that is not too tight. In the event of redness, swelling or even general malaise, it is essential to consult a doctor. If the wound is no longer open, it can be treated with a calendula ointment (marigold ointment).
Blisters on the foot or finger
Blood blisters should definitely heal properly. Therefore, pressure and friction must be prevented. Special blister plasters protect the area. The bladder cannot break or become inflamed. Otherwise, the blood blisters are supplied with special ointments, gels or tinctures.
Home remedies for open wounds
The wound of the open blood bladder can be dabbed several times a day with a sterile compress soaked in chamomile tea. The chamomile tea to be used for this is prepared from a tablespoon of flowers and half a liter of boiling water. After a steeping time of about 10 minutes, the tea is strained and, when it has cooled down a little, can be used for the wound-healing compress. Chamomile has an anti-inflammatory, antibacterial, granulation-promoting and hemostatic effect.
In the acute phase, an oak bark decoction is helpful. For this, a tablespoon of dried oak bark is mixed with a quarter liter of cold water, boiled for about 15 minutes and then strained. Oak bark is anti-inflammatory and antibacterial.
Yarrow is also recommended for wound healing. A teaspoon of dried herb is briefly boiled in 250 ml of water, gently squeezed out and wrapped in a sterile compress, placed on the affected area.
When the wound heals poorly
If the wound heals poorly, the following home remedies can help: Mix equal parts of horsetail tincture, marigold flower tincture and sun hat fluid extract. To treat the wound caused by the blood bladder, 30 drops of the mixture are mixed with half a glass of boiled water and the area is brushed on several times a day.
An equally effective recipe consists of chamomile flower tincture, marigold flower tincture, and yarrow tincture mixed in equal parts. The application corresponds to the above mixture.
This tea recipe also supports the healing process: 20 g chamomile flowers, 20 g marigold flowers and 10 g ribwort. Half a liter of boiling water is poured over a tablespoon of this. After about 10 minutes, the tea is ready and only needs to cool down a little before it can be used for compresses.
Caution - no fatty substances on open wound
Fatty substances such as ointments, quark or creams have no place on open wounds. The edges of the wound can be treated with anti-inflammatory ointments, but these are not to be found on open wounds. This hampers "breathing" and this can lead to infection.
If the bladder is not open - home remedies
If the wound is no longer open or the blood bladder has not opened, the following home remedies can help. All ointments and gels mentioned here should be applied several times a day. A thick ointment bandage overnight supports the healing process.
Cooling helps especially with fresh blood blisters. This will ease the pain a little. The affected area is cooled with ice wrapped in a washcloth or an ice pack wrapped in a towel.
Aloe provides moisture, has a cooling and healing effect. Of course, the plant helps best here. Slit open an aloe leaf and supply the blood blisters with the emerging gel-like substance - but who has an aloe plant at home? In most cases, a gel that contains aloe must be used.
What also works is the application of calendula ointment. Calendula is anti-inflammatory and stimulates the formation of new healthy tissue. Also recommended are ointments that contain both calendula and echinacea (coneflower).
The repeatedly quoted Manuka honey can also be used in the treatment of blood blisters. This special honey supports wound healing.
If the blood bladder is still closed, an arnica ointment can help. Arnica has an analgesic, anti-inflammatory and decongestant effect. However, arnica should never be placed on open wounds.
Healing clay, a well-known home remedy, is also the right choice for blood blisters. This is mixed with water to form a paste and then applied to the affected area. Once the healing earth has dried, it is rinsed off. A porridge made from turmeric powder, mixed with a little honey, has a similar effect.
Zinc ointment is usually used to heal wounds. This also helps with blood blisters.
Blood blisters in your mouth
Blood bubbles in the mouth initially look like small pimples. They can arise both on the tongue and on the gums. Blood blisters in the mouth are caused by minor injuries, for example from chewing hard bread. But allergic reactions to certain foods also cause these unpleasant, painful blisters. Other reasons for this are the lack of vitamin B12 or vitamin C. Excessive alcohol or tobacco consumption can also lead to blood blisters in the mouth.
Usually the small blood blisters heal on their own. They should not be squeezed out as this may cause a secondary bacterial infection to develop. The mouth should be cleaned frequently with suitable mouthwashes and oral hygiene should be taken seriously. Rinsing with Ratanhia mouthwash helps here, for example. Ratanhia has anti-inflammatory and astringent properties. The Ratanhia root was already used by the Incas for oral and dental care.
Calendula essence is also helpful. Diluted with water, it is used to rinse the mouth several times a day. Other home remedies include tea tree oil, which is used to dab the blood blisters. Chamomile tea is also recommended, which is rinsed and also dabbed selectively. Last but not least, painting with myrrh tincture has a pain-relieving and healing effect.
When to the doctor
Large blood blisters, but also smaller blisters that cannot be treated with the help of the mentioned agents and / or are very painful, should be treated by a doctor.
Blood bubbles in the mouth, which are quite small, usually go away on their own. If there is pain and / or your own treatment does not work, you should go to the dentist. This prescribes antibiotic mouthwashes and corticosteroids.
So that there are no blood blisters in the first place
To protect yourself from blood blisters on your feet, it helps to wear silk socks under the actual socks. New shoes are rinsed with hot water and then put on or rubbed with petroleum jelly before they are worn for the first time. The feet are best rubbed with baby powder - this will protect against blisters. (sw)
