Your task is to predict the verdict of a claim based on the provided question-answer pair evidence. The possible labels are: 'Supported', 'Refuted', 'Not Enough Evidence', 'Conflicting Evidence/Cherrypicking'. Justify your answer using the provided evidence and select the correct label.

Claim: Drinking ash of Phyllostachys nigra (black bamboo) mixed with honey and cow’s milk is a potent treatment for COVID-19.

Q1: Is black bamboo used in alternative medicine?
A1: Yes, because 2.1.2 Phyllostachys nigra (Lodd.) Munro Commonly known as “black bamboo”, this is another major species in the genus Phyllostachys. Flavonoids extracted from black bamboo leaves have potent antioxidant activities (Hu et al., 2000; Zhang et al., 2002). Among these flavonoids, flavone c-glucosides and p-coumaric acid reportedly have long retention time in the colon and may contribute to free radical scavenging (Zhang et al., 2007). Luteolin 6-C-(6″-O-trans-caffeoylglucoside), an antioxidant isolated from the leaves, has been reported to protect against oxidative stress-induced cytotoxicity in retinal ganglion cells (Lee et al., 2010). It also enhances the activity of aldose reductase and inhibits the formation of advanced glycation end products, and therefore may potentially have a role in the prevention of diabetic complications (Jung et al., 2007).
Orientin, another antioxidant obtained from the leaves of black bamboo, exerts vaso-relaxant activity through the inhibition of intracellular Ca2+ release and extracellular Ca2+ influx (Fu et al., 2005). Orientin also prevents apoptosis induced by hypoxia and reoxygenation in myocardium and cardiomyocytes. The mechanism for this effect is inhibition of the activation of mitochondrial apoptotic pathway (Fu et al., 2006). These studies suggest potential for cardio-protective effects.

The acetone fraction of the leaves of Phyllostachys nigra (Lodd.) Munro has been shown to enhance leukemia cell differentiation (Kim et al., 2007b), and inhibit interleukin-12 (IL-12) production in lipopolysaccharide-activated macrophages via decreasing NF-kappaB binding activity (Kim et al., 2007a). These preliminary findings suggest potential anti-leukemia and anti-inflammation effects of the acetone extract.

Q2: Can alternative medicines be used to effectively treat Covid-19?
A2: No, because It's a myth
user
justification: QA pair states black bamboo is an alternative medicine and in another states no evidence to support alternative medicines being helpful.
