Gordolobo/Great mullein

1. Respiratory health
Loosening mucus: Mullein is considered an expectorant, meaning it can help thin mucus and make it easier to cough up and expel from the lungs. This can be particularly helpful for conditions with mucus build-up, such as bronchitis, colds, and asthma.
Soothing inflamed airways: The mucilage in mullein can coat and soothe irritated mucous membranes in the respiratory tract, potentially reducing inflammation associated with conditions like coughs and sore throats.
Aiding in conditions like asthma and bronchitis: Mullein is traditionally used to ease symptoms of asthma and bronchitis, although more clinical research is needed to confirm its effectiveness in humans. 
2. Anti-inflammatory properties
Mullein contains compounds like flavonoids and saponins, which may help support the body's natural response to inflammation.
This can be beneficial for various conditions involving inflammation, both internal and external, such as:
Irritated skin conditions like eczema or rosacea.
Joint pain and rheumatoid arthritis.
Swelling due to injuries.
Inflammation in the gut or liver.
Earaches, potentially by reducing inflammation in the ear. 
3. Potential antimicrobial effects
Some test-tube and animal studies suggest that mullein extracts may have antibacterial and antiviral properties.
These studies have shown potential activity against bacteria like Klebsiella pneumoniae (a respiratory infection-causing bacterium), Staphylococcus aureus (a type of staph infection), and Escherichia coli (E. coli).
Additionally, mullein has shown some antiviral activity against influenza and herpes viruses in test-tube studies.
However, it's important to note that these are preliminary findings, and more human research is needed to confirm the effectiveness of mullein in treating infections in people. 
4. Skin and wound care
Mullein has been traditionally used topically to soothe skin irritations and promote healing.
Its emollient properties can help soften and moisturize the skin, while its anti-inflammatory effects can reduce redness and irritation.
It has been used for minor cuts, abrasions, burns, bruises, and conditions like eczema and hemorrhoids.
One human study showed that a mullein cream enhanced the healing of episiotomy wounds. 
5. Other potential benefits (with limited evidence)
Diarrhea: Traditional uses include relief from diarrhea and gastrointestinal cramps.
Pain Reduction: Mullein is believed to have pain-reducing properties, potentially helping with headaches and earaches.
Immune System Support: Mullein contains antioxidants like vitamin C, which can support overall immune health. Some studies suggest mullein may help promote normal immune function by supporting immune system regulation.
