Subject/verb agreement

While reading today's newspaper, I encounter the following sentence in the subheading of a news item:-

A cure for serious ailments with added benefits of smoother, flawless skin, slimmer figure and increased libido are just some false claims associated with traditional medicines.

The subject of the sentence is the part before the verb of incomplete predication 'are'. In fact, the subject is 'cure', the rest being its enlargement.

One will see that a singular noun 'cure' is being matched with a plural verb 'are' here. A correction is, therefore, necessary.

The 'are' can be replaced by its singular equivalent 'is', but the sentence will be awkward as this singular verb is having its complement represented by a plural noun 'claims'.

The logical way will be to change its subject into a plural one and the sentence will sound all right:

Cures for serious ailments with added benefits of smoother, flawless skin, slimmer figure and increased libido are just some false claims associated with traditional medicines.
